Marilyn - Maggie Hyatt mentioned on p.30 of Lillian Horton Altpeter's book. She married Erastus Horton b. 4 Jul 1873 d.after 1960. He was s/o Wallace Horton b 11 Aug 1833 d. 22 Aug 1913 and Sarah Bush. They lived in Warwick (which I believe was in Orange Co NY). No Drowns mentioned in the book nor are there other Hyatts mentioned. Wallace Horton is 8th generation from Barnabas1 Horton, of Southold LI. Hope this helps. Donna Horton
