Anyone who has done family history knows how hard it can be to iron out parentage. With P.P. Brown (aka Ptolemy, Ptolema, Delphus, and P.P. Brown) had three wives and for many years it was unclear who was the parent of which children. Different lines had different theories. Once it was learned he had served in the Civil War a copy of a pension record was requested from the National Archives. A satisfyingly thick set of papers resulted. Inside was a listing of just who the mother of his children had been. There birth, death, and marriage dates. There was also a list of children's names verifying the accuracy of numerous family trees. He filed the papers in March 1898.
