I have done some research on the Goe family line;

Henry aka Harry Goe dob: 1783
Nancy Simpson dob: 1794
children:
William Goe dob: 1817
Henry Goe dob: 1819
Eliza Goe dob: 1820
Male Goe dob: 1824
Jackson Goe dob: 1825
Joseph Goe dob: 1827
Lydia Goe dob: 1828
James P. Goe dob: 1831
Rebecca Goe dob: 1836
Jessica Goe dob: 1837
Elizabeth Goe dob: 1846

Also I found in The Goe Family book the following on page 3, under Generaton II;

2. MARGARET GOE, b. 19 Aug 1727, Prince George's Co, MD m.before 1762, Richard Hutton. In the 1790 censusof Fayette co., Washiington Twp., PA we find Margaret Hutton: one freewhite female...head of family; seven other free persons; and 24 slaves.

In her will she mentions the following listed as 7) My slaves.
a) Old Jeremiah...b)Edward Simpson, a mulatto...a carpenter, has children; c)William...has children; d)Old Catharine ... Edward Simpson is her son; e) Old Rachel...daughter Alice, Old Jeremiah's children by Old Rachelare Benjamin and Leah; f) Hannah...has daughter Anna...son William; g) sarah a mulatto...sons Henry Fitz Edwards and Charles David...one to be a tailor, the other...shoemaker; h)Tobias...; i) Isaac...; j) Philemona... k) Abram... and his half-sisterCassandra...; l)Terrementa...has children; m)Alice...; n) Henriette...; o) Rachel...; p) David, a mulatto lad...to betaught to read and write; q) Susannah...has children.

I want to research the slave records more thoroughly. When I do, I will fill you in on what I find.

Also, I'm guessing you know that George Washington had land in Washington or Fayette county and had a Gilbert Simpson running the place. He also had some slaves working the land.

I don't know if there are any tax records or something showing the slaves names. That would be interesting.

Anyway, will fill you in on what I find.
