Thayer Pedigree Referral Service To request genealogy information, please email me with your full name, your father’s or grandfather’s name, state of birth and birth date if known, e-mail address, and mailing address. If you or your descendants are listed in our 55,000+ names database of Thayers, you will receive a summary of what I have in the database on your respective line. If you or your descendants are not listed, I will work with you to begin research to find them and add to our database.
