There are several Timothys on Tim Geithner's maternal side, so I'm assuming he was named for one of them. But all seem to be namesakes of MA politician & notable Timothy Fuller 1778 (or of one of his namesakes):
http://en.wikipedia.org/wiki/Timothy_FullerTimothy Fuller had a passel of distinguished children:Sarah Margaret (1818) "became the first editor of the transcendentalist journal The Dial in 1840, before joining the staff of the New York Tribune under Horace Greeley in 1844. By the time she was in her 30s, Fuller had earned a reputation as the best-read person in New England, male or female, and became the first woman allowed to use the library at Harvard College."
http://en.wikipedia.org/wiki/Margaret_FullerAs a foreign correspondent for the Trib (first woman) she met the Italian revolutionary Mazzini & became pregnant by his follower the Marquis Ossoli, fled Italy when France invaded, & died with Ossoli & their child in a shipwreck off Fire Island the same year.
Ellen (1820) married the transcendentalist poet William Ellery Channing (Harvard).

Arthur Buckminister (1822) (Harvard, Harvard Divinity) became a Unitarian pastor & died in the Civil War. His grandson (& Tim Geithner's maternal grandmother's second cousin) was
Buckminister Fuller (1895).

Frederick Timothy's (1850) daughter
Lucy married the "millionaire clubman & philanthropist"
Philip Cabot, a "real estate trustee & investor".
Cabot was a nephew of "Senator Lodge," I assume Henry Cabot Lodge:

Philip was also an investment banker with White, Weld:

Another of FT Fuller's daughters married the prolific artist/illustrator
Griswold Tyng:http://americangallery.wordpress.com/2010/01/01/griswold-tyng-1883-1960/Tyng's granddaughter
Susan Farmer was a two-term Secretary of State of Rhode Island (RI's first female) starting in 1983 & the long-time director of RI's PBS station.

Philip Marquand (1867), and their son was the writer
John Phillips Marquand (1893):
http://www.harvardsquarelibrary.org/unitarians/marquand.htmlMarquand was creator of this literary icon:
Marquand's first wife was
Christina Sedgwick, niece of the editor/owner of the Atlantic Monthly
Ellery Sedgwick:http://en.wikipedia.org/wiki/Ellery_Sedgwickand first cousin to the father of this Sedgwick:
http://en.wikipedia.org/wiki/Edie_SedgwickMarquand's second wife was
Adelaide Ferry Hooker, whom he met while touring China in 1934-35. His bride-to-be was also touring China, with the "Garden Clubs of America".
Interesting time to tour China.
http://www.garethjones.org/Canada2007%206_files/frame.htm#slide0309.htmOn her mother's side she was Ferry-Morse seed; on her father's side she was Hooker Electro-Chemical. IOW, great wealth on both sides.
Adelaide Hooker's sister was
Blanchette (1909).
http://en.wikipedia.org/wiki/Blanchette_Ferry_HookerShe was the wife of
JD Rockefeller III, brother of
David (1915), the only living grandchild of JD I.
JD III founded the Asia Society:
http://en.wikipedia.org/wiki/John_D._Rockefeller_III Blanchette & JD III were the parents of
"Jay" Rockefeller (1937), current Senator from West Virginia.
Peter F Geithner, Tim's father, is an advisor to the Asia Society, as well as the Rockefeller Foundation & the China Medical Board, all Rockefeller creations.
