Hi
The Ernest Greaves who married Edna Murgatroyd in Western Australia in 1913 looks to have returned to England in 1926 with his wife and children, returning to Western Australia in 1927. The UK address on the passenger lists for 1926 and 1927 was Great Horton, Bradford, Yorkshire. There is a death for an Ernest Greaves age 74 in Western Australia in 1965, father Joshua, mother Ann.
The 1901 census has an Ernest Greaves born Pudsey, (which is in the Bradford Registration District) Yorkshire in 1890, son of Joshua and Ann. I think this is the Ernest Greaves who emigrated in 1911.
