There were other children, who died young and whose names I don't know. I believe that Ester never married.
Martha's father William and James's mother Elizabeth were brother and sister.

With only initials, it is difficult to tell which is Martha, but the 1870 census and my knowledge of the family will help identify them. S. E. is Sarah Ellen "Sallie;" M. I. is Malinda; M. F. is Martha; J. A. L. is Jo Ann; and M. A. is Mariah Adeline
