Margaret Doby's father (Alsey) is my great...grandfather. I found these notes that I made a few years ago and then gave up on him. It might help.....
Ransom Cranford married Margaret Doby 31 Jul 1847 in Davidson Co., NC. Ransom Cranford also married Nancy Linnens 8 Jul 1854 in Randolph Co., NC. Have never found Ransom Cranford on a NC census index 1850, 1860, 1870.
Found a Ranson Crawford age 44, Greensboro PO, Guilford Co., NC,
1860 census, pg. 147, visitation no. 1014. Wife named Nancy age 32-
children: Jane age 13, Elizabeth age 8, Martha age 6, George W. age 5,
Susan age 5/12.
Then in 1870 found a Ram Cranford (Crawford on index) age 50, Hill Twp., Montgomery Co., NC, pg 408, visitation no. 53. With wife Nancy age 40-children: Martha age 14, Susan age 8, Roxana age 7, Henry age 4, ? Bleu age 2 a female.
Then consider Ransom Cranford married in Randolph County to Nancy Linnens on July 8, 1854. Look at Martha and Susan both on 1860 and 1870 census with the multi-named Cranford and wife Nancy in both cases.
It appears this Ram, Ranson and Ransom Cranford (Crawford) most likely the same and wife Nancy and two of the children match up. Suspect Ransom's first wife Margaret Doby died 1852 or 1853. The older children in 1860 named Jane & Elizabeth most likely the children by this first wife Margaret.
