Node Chart for Descendants of John CORBIN (1671-1748) of Richmond Co., VA

Diana, Goddess of the Hunt — for Ancestors!

With the testing of enough cousins, a genetic "tree" of a progenitor's descendants can be constructed showing where in each lineage mutations have occurred. Such a tree can be extremely useful in supporting (or debunking) paper genealogies. A node chart can only represent what you know at the time with the data you have (which is true of everything, really), so it's expected that the chart will be modified with each advance in DNA results and with advances in paper genealogy.

All of the individuals in the table below are matching at levels indicating, beyond any doubt, they have a near common ancestor. I am making an assumption here that that ancestor is John CORBIN of Richmond Co., VA, which means that is the hypothesis we are testing. It may, in fact, be the case that their common ancestor is futher back, but until we test someone with a solid paper trail going back further, the current hypothesis is the only one available to test.

Ideally, we would test every living patrilineal male descendant of John CORBIN of Richmond County, and I'm not going to give up trying to find and test them all! If you are such a male, please join the project and be tested.

Y-DNA STR Node Chart for the Patrilineal Descendants of John CORBIN of Richmond Co., VA

Generations from Progenitor										Remarks
0	1	2	3	4	5	6	7	8	9	Remarks
John b. 1671	Rawley b. 1697	Jeremiah b. ca. 1718	Martin b. ca. 1743							Testing of a descendant of Martin would tell us whether or not Jeremiah possessed the CDYb mutation.
			Martin or David Scott	unknown	Elliot b. ca. 1812	George Washington b. 1844/5	William Franklin b. 1887	Pvt	#143803 CDYb = 37>36 DYS511 = 10>11	This individual shares a mutation at CDYb with #119547, so he must at least descend from Jeremiah, if not David Scott or Jesse. He has also acquired an additional mutation downstream of his connection to the line of #119547.
			David Scott b. 1745	Jesse b. 1764	Richard b. 1804	Elliott b. 1848	Arthur Willet b. 1895	#119547 CDYb = 37>36		This individual has accumulated one mutation in his descent from Rawley, a mutation he shares with #143803. We don't know where in his line this mutation took place, but it had to have been downstream of Rawley and upstream of Richard.
		Thomas b. 1721								-
		Ambrose b. 1729	Joshua	William Singleton	Estill Wade	William Azariah	Ben Sory	Pvt	#147715 DYS385a = 14>13 GATA-H4 = 10>11	This individual has acquired two mutations in his descent from Rawley.
	unknown	unknown	unknown	James b. 1781	Pinckney b. 1836	James Thomas b. 1859	Lawrence Pinkney b. 1892	Pvt	#77012 DYS448 = 20>19 DYS641 = 11>10	This individual has acquired two mutations in his descent from a son of John. A connection to Ambrose is claimed. Results, so far, neither support nor refute such a connection.
	unknown	unknown	Peter b. 1745	George Lee b. 1763	James Madison b. 1800	Garnett b. 1844	James Madison b. 1873	Pvt	#120035 DYS389ii = 28>27 DYS534 = 16>17	This individual has acquired two mutations in his descent from John.
	John Jr. b. ca. 1698									-
	William b. ca. 1699									-
	Charles b. ca. 1702									-
	Andrew b. ca. 1715									-
	David b. ca. 1717									-
