I am the son of Rita Murtagh, a sister of Ethel which I think makes us cousins? Yes I know some of the answers to the questions that you have asked. From our research Thomas's full name was Thomas Isaac Genese Murtagh. You are correct about the Levenston's. The Curedale history appears in Wikipedia including our mutual relatives.
