One of the participants in the Floyd DNA project is a descendant of Isaiah Floyd b c 1843 Clinton Co OH > Center Point, IA. He is on the 1850 Marion/Clinton/OH census with mother Elizabeth Ann Nicely with 3 siblings. In 1860 Elizabeth remarried to Samuel Smith and the family is in Center Point, Linn IA. Theory that Elizabeth Ann Nicely may have married James Floyd, found in the 1840 census but not 1850, near the Peter Nicely (E A's father). There is also a Joseph Floyd from Clark/Clinton/OH, who appears to be a son of Lewis Floyd, and he also has a son named Isaiah, in 1860 Center Point, Linn, IA. The Floyd DNA project does not currently have a match for Isaiah Floyd nor any known testers from William Floyd. http://www.halcyondays.com/floyd/floydtestcomparison.asp?kitno=N87916http://www.halcyondays.com/floyd/floydtestcomparison.asp?kitno=N87916 If you are a direct line male Floyd from the line of William Floyd or known through Lewis, Joseph, or any other known sibling, please consider joining the Floyd YDNA project.
