Though there is no documentation that I have found to positively identify this grave as being Martha J. (Sellers) Bonham, there are strong clues. The last child Martha Sellers is known to have had with Nehemiah Bonham was Charles Bonham (b. 1874). The next child born to Nehemiah was Vashti Bonham (b. 1879) , her mother was Martha (Jones) Bonham. I have found, in Buncombe county N.C., a listing for the grave of a Martha Bonham, born 1838 and died 1876. The birth date coincides with the birth year calculated from the census reports for Martha Sellers Bonham. The date of death in the information falls into the years between the last child of Martha Sellers Bonham and the first child of Martha Jones Bonham, the grave is also in the county, near the town, that the Nehemiah Bonham family was know to have lived. These clues, when taken as a whole, make me confident that this is the grave of Martha Sellers Bonham.
