There is the possibility that Martha Gower also went by the name Martha Kinney who was born the same year as Martha Gower. Martha Kinney was daughter of Mark Kenny and Myrtle Gower,born after Marks death. Myrtle Gower was elder sister of Robert John Gower father of Martha Gower. When Myrtle remarries to a Mr.Marriott she is not in 1921 census of their household. But a Martha Gower shows up living with Robert Gower at his parents residence in Huron Co.,Mr. William John Gower and his wife Margaret Adair Gower. Therefore it is probably likely that Martha Gower/Martha Kinney are the same person. She may have resided in On. as she grew up or went West with her father Robert John Gower who first moved to Manitoba and eventually British Columbia. He left On.circa 1928 to live out West,not sure if Martha moved with him. Anyone who can assist in discovering what happened to Martha please let me know.
