From the DAR record we see that Stephen Tompkins was first married to Hanna Unknown - the date of the marriage and the date of Hannah's death is unknown.
Stephen then married Sarah Sarles in 1772. I cannot find any sources at all that support the marriage date of 1772. All of the known children are attributed to this marriage but the problem is that the first three children, Hannah, John, and Stephen Jr., are born in 1761, 1771, and 1772 - all impossible for parents who were married in 1772.
Additionally, Hannah's name is Hannah Sarah Tompkins, very likely her first name is a tribute to the first wife of his father and her middle name a tribute to her mother. I also cannot find a source for the birth year of 1761 for Hanna. Considering that all of the children are born in regular succession from 1772 onward, I wonder if she was born in 1771?
