Welcome to DU Midlandsdawg. I think you're thinking of Margaret MacDonald who was "amongst the demonised false prophets who were causing "disturbances" in Edward Irving's church at the time". The trouble is, there's nothing pre-tribulationary in Margaret's vision; her revelation seems to lean more towards post-trib.
http://www.apostasynow.com/topics/trib/pretrib08.html Gawd I hate this theory. You can't argue with the Rapturists- it's as if their minds/brains have already been raptured away! A total waste of time.

Two religious sects in Britain took up Margaret’s idea. One was the Catholic Apostolic Church headed by Edward Irving (1792-1834). This sect believed that because the Second Coming was imminent, they had the gifts of the spirit, such as prophecy and speaking in tongues, as the apostles did.
The other group that adopted Margaret Macdonald’s idea was the Brethren or Plymouth Brethren organized by John Nelson Darby (1800-1882). Darby was educated as a lawyer, became an Anglican priest in 1826, but went on to found the (Protestant) Plymouth Brethren in 1830. Darby visited the Macdonald home in 1830 and first presented the new pre-tribulation rapture doctrine soon thereafter. The new doctrine was not received unanimously.

From 1862 to 1877, Darby lived in and traveled throughout the United States and Canada, spreading his message. He was a very appealing speaker and also intolerant to criticism. At first he tried to win members of existing Protestant congregations to his sect, but met with little success. He then spread his end-times message to influential clergymen and laymen in churches in major cities without insisting they leave their denominations.
Two of his converts were James Hall Brookes, pastor of the Walnut Street Presbyterian Church in St. Louis and Adoniram Judson Gordon, pastor of Clarendon St. Baptist Church in Boston. These two men became leaders of the movement which spread the doctrine throughout the northeast and Midwest during the last quarter of the 19th century. Dwight L. Moody also accepted the doctrine.
From 1883-1897, each summer at Niagara-on-the-Lake, Ontario, James H. Brookes led conferences which spread the doctrine very successfully to conservative church leaders of America who were concerned about the liberal influence of "higher criticism" that was making inroads into churches. The new message spread from the leaders down to the local congregations.
In 1897 there was a split of conference participants into two groups: a pro-Darby faction led by Arno C. Gaebelein and Cyrus I. Scofield, and an anti-Darby faction led by Robert Cameron. A five-year "paper war," in which each side wrote articles blasting the other side, ended in a win by the pro-Darby forces.

http://reformed-theology.org/html/issue06/pre-trib.htm Darby expressedly denied that Ms. MacDonald's vision had any authority, and in a letter written in 1845, he condemns "Irvingism" as a "fatal error". Neither have I discovered, after reading 1500 pages of Darby's personal correspondence, any reference to Lacunza or his book. It may well be that he heard of 'a Rapture' before he began to teach it, but I have not been able to find a formal treatise on The Rapture written by Darby: and "Rapture Doctrines" were NOT his main interest anyway! The earliest formal presentation of what may be called "the Scofield scenario" of a Pre-Tribulation Rapture I have found was written by a William Kelly, a friend and associate of Darby's. But Scofield got his Rapture Doctrine from Darby, as Scofield himself and others have testified. Darby, who eventually resigned from the Anglican Clergy; from then on refused to confirm any denominational creed or to apply for or accept any kind of preacher's "license". He also denounced all religious bureaucracies as contrary to the scripture and the rule of the Holy Spirit; sarcastically labeling them as "The Establishment". Thus, he was eventually branded as a proponent of ANARCHY. Even his enemies can find little to say against him, since his morals, his public conduct, his financial affairs, and his intellectual genius were above reproach. Some of Darby's contemporaries testified that he gave away 90% of his income, mostly to poor people. He translated the Bible into French, German, and English, and his French version is still the most respected translation in France to this day. His English version was so accurate, that the corrected renderings of the Revised Version of 1881 and the American Standard Version of 1901 are virtually reproductions of Darby's work. Darby is a paradoxical character like none other in the 19th century; for while he is arguably the most influential theologian since Martin Luther, almost no one even knows he ever existed, and almost no one knows that Scofield learned The Rapture Doctrine from John Nelson Darby.

I can't read the thing but if you or anyone else wants to read her vision, it seems to be quoted here:
MARGARET'S REVELATION "It was first the awful state of the land that was pressed upon me. I saw the blindness and infatuation of the people to be very great. I felt the cry of Liberty just to be the hiss of the serpent, to drown them in perdition. It was just 'no God.' I repeated the words, Now there is distress of nations, with perplexity, the seas and the waves roaring, men's hearts failing them for fear. Now look out for the sign of the Son of Man. Here I was made to stop and cry out, O it is not known what the sign of the Son of Man is; the people of God think they are waiting, but they know not what it is. I felt this needed to be revealed, and that there was great darkness and error about it; but suddenly what it was burst upon me with a glorious light. I saw it was just the Lord himself descending from Heaven with a shout, just the glorified man, even Jesus; but that all must, as Stephen was, be filled with the Holy Ghost, that they might look up, and see the brightness of the Father's glory. I saw the error to be, that men think that it will be something seen by the natural eye; but 'tis spiritual discernment that is needed, the eye of God in his people. Many passages were revealed, in a light in which I had not before seen them. I repeated, 'Now is the kingdom of Heaven like unto ten virgins, who went forth to meet the Bridegroom, five wise and five foolish; they that were foolish took their lamps, but took no oil with them; but they that were wise took oil in their vessels with their lamps.' 'But be ye not unwise, but understanding what the will of the Lord is; and be not drunk with wine wherein is excess, but be filled with the Spirit.' This was the oil the wise virgins took in their vessels - this is the light to be kept burning - the light of God - that we may discern that which cometh not with observation to the natural eye. Only those who have the light of God within them will see the sign of his appearance. No need to follow them who say, see here, or see there, for his day shall be as the lightning to those in whom the living Christ is. 'Tis Christ in us that will lift us up - he is the light - 'tis only those that are alive in him that will be caught up to meet him in the air. I saw that we must be in the Spirit, that we might see spiritual things. John was in the Spirit, when he saw a throne set in Heaven. But I saw that the glory of the ministration of the Spirit had not been known. I repeated frequently, but the spiritual temple must and shall be reared, and the fullness of Christ be poured into his body, and then shall we be caught up to meet him. Oh none will be counted worthy of this calling but his body, which is the church, and which must be a candlestick all of gold. I often said, Oh the glorious inbreaking of God which is now about to burst on this earth; Oh the glorious temple which is now about to be reared, the bride adorned for her husband; and Oh what a holy, holy bride she must he, to be prepared for such a glorious bridegroom. I said, Now shall the people of God have to do with realities - now shall the glorious mystery of God in our nature be known - now shall it be known what it is for man to be glorified. I felt that the revelation of Jesus Christ had yet to be opened up - it is not knowledge about God that it contains, but it is an entering into God - I saw that there was a glorious breaking in of God to be. I felt as Elijah, surrounded with chariots of fire. I saw as it were, the spiritual temple reared, and the Head Stone brought forth with shoutings of grace, grace, unto it. It was a glorious light above the brightness of the sun that shone round about me. I felt that those who were filled with the Spirit could see spiritual things, and feel walking in the midst of them, while those who had not the Spirit could see nothing - so that two shall be in one bed, the one taken and the other left, because the one has the light of God within while the other cannot see the Kingdom of Heaven. I saw the people of God in an awfully dangerous situation, surrounded by nets and entanglements, about to be tried, and many about to be deceived and fall. Now will THE WICKED be revealed, with all power and signs and lying wonders, so that it it were possible the very elect will be deceived - This is the fiery trial which is to try us. - It will be for the purging and purifying of the real members of the body of Jesus; but Oh it will be a fiery trial. Every soul will he shaken to the very centre. The enemy will try to shake in every thing we have believed - but the trial of real faith will be found to honour and praise and glory. Nothing but what is of God will stand. The stony-ground hearers will be made manifest - the love of many will wax cold.
I frequently said that night, and often since, now shall the awful sight of a false Christ be seen on this earth, and nothing but the living Christ in us can detect this awful attempt of the enemy to deceive - for it is with all deceivableness of unrighteousness he will work - he will have a counterpart for every part of God's truth, and an imitation for every work of the Spirit. The Spirit must and will be poured out on the church, that she may be purified and filled with God - and just in proportion as the Spirit of God works, so will he - when our Lord anoints men with power, so will he. This is particularly the nature of the trial, through which those are to pass who will be counted worthy to stand before the Son of man. There will he outward trial too, but 'tis principally temptation. It is brought on by the outpouring of the Spirit, and will just increase in proportion as the Spirit is poured out. The trial of the Church is from Antichrist. It is by being filled with the Spirit that we shall be kept. I frequently said, Oh be filled with the Spirit - have the light of God in you, that you may detect Satan - be full of eyes within -be clay in the hands of the potter -submit to be filled, filled with God. This will build the temple. It is not by might nor by power, but by my Spirit, saith the Lord. This will fit us to enter into the marriage supper of the Lamb. I saw it to be the will of God that all should be filled. But what hindered the real life of God from being received by his people, was their turning from Jesus, who is the way to the Father. They were not entering in by the door. For he is faithful who hath said, by me if any man enters in he shall find pasture. They were bypassing the cross, through which every drop of the Spirit of God flows to us. All power that comes not through the blood of Christ is not of God.
When I say, they are looking from the cross, I feel that there is much in it - they turn from the blood of the Lamb, by which we overcome, and in which our robes are washed and made white. There are low views of God's holiness, and a ceasing to condemn sin in the flesh, and a looking from him who humbled himself, and made himself of no reputation. Oh! it is needed, much needed at present, a leading back to the cross. I saw that night, and often since, that there will be an outpouring of the Spirit on the body, such as has not been, a baptism of fire, that all the dross may be put away. Oh there must and will be such an indwelling of the living God as has not been - the servants of God sealed in their foreheads - great conformity to Jesus - his holy holy image seen in his people - just the bride made comely by his comeliness put upon her. This is what we are at present made to pray much for, that speedily we may all be made ready to meet our Lord in the air - and it will be. Jesus wants his bride. His desire is toward us. He that shall come, will come, and will not tarry. Amen and Amen Even so come Lord Jesus.''
