If anyone is related to the Trevalion (varous spellings) family in Dorchester County Maryland I have traced a bit of their ancestry back to York county Virginia and from there to Brabourne Kent England. I have found the baptismal records of John, Thomas and Edmund Chisman (Cheeseman) in Braborne Kent and their father's name Thomas. Edmund Chisman's daughter married Robert Curtis of York Co Va. whose daughter Jane m. John Trevalion. They moved to Dorchester at some point. I have more detail if anyone is interested.
