All Those Releases of Dower

If your ancestor bought and sold property after property, the deed work can be tedious. However if he were married during those land transactions, his wife would have had to "release" her dower when the property was sold. The name of the wife on those releases could provide clues as to the existence of more than one wife and approximately when he was married to which one. A Mary releasing dower in 1802 and 1805 and a Susannah releasing dower in 1810 and 1817 could be a good clue.
