I saw your post while researching my family tree; my mom was Mary Dodd born 1920 in St. John's, Newfoundland. I have traced back to my great-grandfather , Mathew /Matthew DODD born about 1845, married Johanna Nowlan/Nolan. I've been trying to put together the connection to Thomas Dodd, which as you mentioned is the earliest Dodd. I remember my mom saying the family came from England...how are you related?
