My research does not have Thomas Humphryville married to the daughter of Philip Turnor. Thomas married Hannah Annie Turner, the daughter of Joseph Alexander Turner and Emma Good. Joseph was a son of Philip Turnor and Elizabeth Wapisk. My research is from the Hudson Bay Archives, the book Across the River by Pearl Weston and the research of Gail Morin, A compendium of Metis Families, Descendants of Edward Humpherville; Vol. III & Descendants of Joseph Turner, Vol. V.
There seems to be an ongoing discrepancy over the correct Hannah Turner. One was born in 1790 and the other (the one married to Thomas Humphryville) was born in 1804 and was married off as a child bride.
