I cannot discover who Mary Margaret Parsons was living with 1910-1913 when my father (Albert Edward Charles P.) and uncle (Ernest Alick Henry P.) were born. She was living in Bourke at the time. She had divorced James Walters in 1906, and was known to be living with William Honeyman in Queensland from 1917.
It's possible it was a Walter Hopley - found some nespaper references to him living with a Mary Parsons, but there were two Mary Parsons in Bourke at that time. Don't know which one he is attached to.
