Most likely you came from where most of Thomas folk came from and that is Saint Mary's, Maryland. Before 1635, most records indicate Wales by way of England for a hand full of centuries. We sometimes came to America as indentured servants, sometimes we came as our own masters. The Ark and Dove were are first recorded journeys. We started leaving Maryland, by the masses, after the Revoluntianry War. We mostly went to the pioneer front lands. My branch settled in Marion county , KY. Notice the use of Mary in Marion. Use the name Mary in your searches to know you could be on the right path. Church records always are helpful. We were mostly Catholic. Census records have been the best guide for me.
