Hello Eric, this message was posted 4 years ago, so I hope you are still interested in your family history.I have a connection to the Trenwith family in Brant, Ontario. My 2x grt grandfather William Thompson had a sister Sarah who married George Frederick Trenwith in England.Their son also George F went to Canada. He married Hannah Cox; they had 3 children, William F born 1895; Edith Alice b 1898 & Edward George b 1899. William F married Mary Matilda Fitze in 1917. Does this sound like your family?I have a bit more information from Canada, but would love to make contact with some living Trenwith descendants.
