I,too, have been researching for the parents of Zachariah, Thomas and Joseph.The only possibility that I can find listed is Zachariah Allen, b. 1730-1734 in Rowan Co., NC who died 9-27-1789 in Rowan co.His wife's first name was Sarah.They may have also lived in Orange co., NC.
My Joseph was born abt. 1755 making him the eldest of these boys.He married Jan. 30, 1779 in Guilford co. to Eleanor Dilworth.He died between 1824-1830 in Davie Co., NC.They were the parents of 11 children.Their son, William, b. 1782 in Lincoln Co., NC, is my direct ancestor.He married 10-22-1823 in Rowan Co. to Milly Etchison.He died August 1849 in Davie co.William and Milly were the parents of 11 children.Their son, Joseph, is my direct ancestor.He was b. 1811 in Rowan or Davie co., NC.He married in 1835 to Nancy Smarr Kinnick.In 1850 they left NC to move with some of Nancy's family to Johnson Co., In.Joseph died April 13, 1882 in Johnson co., In.Joseph and Nancy were the parents of 8 children whose descendents are sill in the Johnson co., In area.I have a lot of information on many descendents of Joseph and Eleanor which I am happy to share.I have a butter dish (glass, oval) and a library table that were brought from NC to In in 1850.These were handed down to me at the death of my grandmother who had gotten them from her mother.
