Kathryn, We do not have this marriage.Do you know where and when it occurred?We also do not have anyone matching Martha's date of birth in Lincoln Co. TN in either 1850 or 1860. Do you have a copy of her death certificate (or did she have one)?If she had one, it should list her parents' names. If she didn't have one, maybe the local newspaper printed an obituary which mentioned her survivors? The only marriage in Lincoln Co. TN of a Martha that we have is that Of Martha Alford to James M. Buchanan, Nov. 30, 1870. What were her children's names? Did she live in Lincoln Co. until her death?Were there any probate records which could mention relatives? These could be a clue to her ancestry.
