William Dugger made his Will on 10 Apr 1839 in Carter Co., TN naming his heirs. The very first one named was "my daughter Anna Willson."
Unfortunately that is all we know of her. Robert T. Nave believes her husband was named Joseph Wilson and that they went to Kentucky with her brothers (that would be Knox Co., KY, if correct). If she did make that move, she may also have followed them on to Greene Co., IN.
