I am trying to help another person with her Faris-Farris line out of York. She descends from Tirzah Clarke Faris who married Thomas McGill Boyd. In looking at my records, I noticed I also have one of TIrzah's sisters Martha M. Faris married to a Thomas M. Boyd. Were both of these sisters married to Thomas McGill Boyd or do I have some erroneous information here? Thanks, Wanda
