Illustrating the peril of accepting digital databases at face value, these two pedigrees purport to show the ancestry of the same individual. Martha Thomson and revolutionary veteran Ensg. Isaiah Blood of Bellingham, Norfolk, Massachusetts are my 6th-great grandparents. The first chart depicts data downloaded from the LDS church website (familysearch.org); and the second from the widely published "World Family Tree" (FTM CD #715). If anyone has documented information, with source citations, that they would be willing to share about Martha's family and ancestors, I would very much appreciate hearing from you!
