Matthew McElroy is listed as a neighbor in the property description. We find Thomas Taylor in the South Beaver Twp, Beaver County, census. One girl under 10, and two parents 26-45. Thomas would be 27, using 1773 as his date of birth from his tombstone. We don't know the date of birth of Agnes at this time.
Family is in Beaver County, PA, census.
James Taylor is born, per his biography. War of 1812. We have no record that Thomas, or any of his older sons, were involved at this time. This seems consistent with the age progression from the earlier Beaver Co Thomas Taylor family, and although we can't exactly calculate to the sixteen children alluded to in a family letter, it shows a large family in that ball park. Apparently a deed had never been filed to properly reflect the inheritance by Thomas Taylor of the land he inherited from John Taylor.
