[3] His final wife was widow and heiress Hannah Jones Williamson, whom Coalter married in February 1822 and who survived him.

After serving as the Commonwealth's Attorney (prosecutor) for several years, Coalter was appointed to the General District court for Staunton in 1809.

After marrying the widow and heiress Hannah Jones Williamson the following February, Coalter also operated and occasionally lived at "Chatham Manor" near Fredericksburg, Virginia, which his fourth wife actually inherited from her father William Jones after his death in 1845, years after Coalter's death.

His and his last father-in-law's demise led to legal complications, as his widow Hannah Coalter wanted to free the slaves she inherited, which was not permitted at the time, although she had drafted a will to expressly permit such (and to ensure the freed slaves would not drain government resources as required by statute) and had it redrafted by acclaimed lawyers before she died in 1857.

Hannah had a very much younger half-sister Betty, who married one of the slaveholding Lacy brothers who operated Ellwood and wanted Chatham as well.
