Have you found Joseph and Rebecca in 1850 census?I have not been able to locate them.
And what is your take on the 1860 census, Abbeville, SC, Joseph age 37, Rebecca age 27, James age 12 (not in 1870, died in Civil War?), John age 10 (ditto), Thomas age 8 (is this David Calvin?), no Margaret nor Noah at all. In my grandmother's notes, she notes the death of MRS. Margaret Alewine.Was she possibly a daughter-in-law, instead?
1880 census has Joseph and Rebecca with James P age 3 and George age 1.Was Rebecca having children at age 50, or are these grandchildren perhaps?
My line is their son John Lewis Alewine b1869, who married Philadelphia Childs Aug 11, 1896 Franklin County, GA.
