Hi Lynn - I'm the person who has the Bird/Burd of New Jersey website, even though it's broken right now and I haven't had time to fix it. According to my notes, your Sarah was the daughter of Jacob Burd and Wilemte Anna Cunnningham. Jacob was the son of Elisha Bird and Elizabeth Snyder, and it leads back to my line. If you send me your email address I can send you a gedcom of the family, or a family history report.
