I interpret the above document as meaning that Alexander Forgey's wife went back to her father? I found an Agnes Forgy marrying a James Rogers on 26 Apr 1789 in Washington County, VA. I don't know whether that is a reference to his daughter? By the way Anne is a nickname for Agnes.
The land sale below seems to confirm that he didn't have a wife in 1795. All of the other sales on the page refer to husbands and wives.
These are some of my sources for Alexander Forgey.
