No, she was the second Mother in the family. The first was in a mental Hospital from 1925-26. She left NZ under her maiden name, with an older daughter (about 5 years old), also under her Mother's maiden name. I suspect that she came here with her daughter, as I can't find her birth certificate anywhere. And then she left a few years later, with her daughter, and left her 3 year old son with the father. Perhaps the father changed the son's name after the mother left. Not sure what happened.
