I'm tracing my Shockey family of Morgan County and am stuck with the parents of Nancy Snyder Shockey, (wife of John Shockey) b. 1796 d. 1874. Her death certificate lists parents as F. and E. Snyder. I thought they might be Frederick Snyder and Elizabeth Pennybacker who married in Berkeley County (now Morgan) 25 January 1785. A Frederick Snyder was taxed in 1787 in Berkeley in with other Morgan County names. A Frederick Snyder appears in the 1820 and 1830 census in Morgan County. Elizabeth Pennybacker Snyder moved to Vinton County, Ohio and applied for a widow's Rev. War pension in 1850 stating that Frederick had served in the war from Hagerstown MD and died in 1840. However, in the 1820 census there were also two more Frederick Snyders close by, one of Jefferson County and one in Frederick Co. To complicate it more George Washington Shockey is quoted in a letter stating that his grandfather was Frederick Snyder of Hampshire Co. who moved to Vinton County, Ohio in 1821. If that is the case, who was the Frederick Snyder still in Morgan County in the 1830 census? I show these Snyder marriages in Morgan County:

John Snyder m. Catherine Henry 25 Sept 1822 (this is also my line)
Frederick Snyder m. Nancy Richardson 24 Nov 1823
Jacob Snyder m. Mary House 3 July 1836
John Snyder m. Catherine High 30 May 1829, with Frederick Snyder as bondsman.

Can someone help me sort this family out? They don't seem to have stayed around as I find no Snyders/Sniders in the 1840 or 1850 census in Morgan County. I also have an autosomal (extremely high) DNA match with a Catherine Snyder b. 1784 m. Henry Simmons from Pendleton VA.
