Individual Details

Even though the Nissan-Siegen book and other references state that there were no children by Susanna McGee, I found Breckinridge Court records of guardianships for the young daughters Hannah and Lucinda which do indeed indicate they were likely daughters of Susanna. Had they been daughters of WinnieAnn, born before the marriage to Susanna, they would not have needed a guardian.

A deed of 1834 shows that Susanna remarried after the death of William Hardin. She is listed among his heirs as Susanna Armstrong, wife of Robert Armstrong. I did find a Robert Armstrong in Breckinridge Co but only in the 1840 census - he wasn't there by 1850.
