I have Shadrach's dates as 1766-1840 and Elizabeth's as 1773-1813. I don't have a place of death for either of them. Nor do I know Shadrach's parents. In a grandson's bio it says "his first ancestor in America was Henry Corbin, of Warwickshire, England, who settled in Westmoreland County, Virginia, in 1650". Shadrach and sons are in Huntingdon County, PA in the 1830 census. Shadrach's 7 children as named in the probate of their [maternal] grandfather David Proudfoot (christening dates from church records) were: Eliza CORBIN Abraham CORBIN christened 22 Aug 1796  David CORBIN christened 24 June 1798 Nathan CORBIN christened 1 Sep 1800 John CORBIN b. 1803 Agnes CORBIN christened 27 April 1806

•  The descendants of the illustrious Henry CORBIN of Hall End, Warwickshire, and Virginia are well known, and Shadrach isn't one of them (the grandson's bio in The History of Posey County, Indiana, was in error).  Shadrach's father, Nathan CORBIN, was one of the Guernsey/Balto CORBINs, and Y-DNA testing has shown the Guernsey/Balto CORBINs are not remotely related to the Hall End CORBINs.  Also, the given names Shadrach, Abraham, David, and Nathan are common among the Guernsey/Balto CORBINs, but I've not found them in the Hall End CORBINs. •  Where's Delilah?  Isn't she the 7th child?  Or did I err in copying this post?  I could check, but I can't pull up this message at the old CORBIN GenForum board.  These boards were purchased by Genealogy.com, which is now owned by Ancestry.com, both of whom managed to ruin the best genealogy message boards we ever had.
