Joseph was born about 1845 although I don't know if it was in Australia. He married Mary Jane Muir in 1884, she was born in Timor, Victoria in about J1820
I found Australia electoral rolls with J.M.Williams where he resided in 1909 and 1912 in Laanecoorie, Victoria, Australia. Then from 1913 to 1917 he resided in the Grampians, Victoria, Australia.
Joseph and Mary Jane had a son named Joseph Graham Williams 1864 - 1930, born Maryborough, Victoria.
He died in about 1920 in Moonee Ponds, Victoria, Australia.
I don't have access to ancestry or other paid groups and I'm having a very difficult time locating information. On Mary Jane Muir's side I have gone further back than 1500, although I'm not qualified to enter this information. I'd love to match up the Williams side as well.
If someone can help I'll be very grateful.
