I hope this thread is still active. I have a Trezise g-grandmother from Cornwall and would be most appreciative if anyone can shed some light on her parents. Her name was listed as both Josepha and Sophia Trezise. She was born in 1821 and married David Stephens, son of David Stephens. I found her in the 1841 census as Sophia Stevens, married, 20, but David was not listed with her. She is living in someone else's household. They later moved to the U.S. as I have found them in censuses in New Jersey. They may have at some point later moved to Pennsylvania. I have a note her father may have been William but not sure when or why that was noted. Thanks!
