Shirley, The community of South Worcester is in Otsego County. It lies in the southwestern corner of the Town of Worcester and lies on the north bank of Charlotte Creek which defines the boundary between Otsego and Delaware Counties. To further confuse the issue, Schoharie County's westernmost tip lies about a mile or a mile and a half due east. Someone who's records say they lived in South Worcester may well have actually lived in Schoharie or Delaware but gone to church in South Worcester. That's also probably why you got conflicting answers to your initial query. I hope this clarifies things for you. Best regards, Kelvin Kean Elverson, Pennsylvania
