I am looking for anybody that may have information on the father of Donald Gilbert Usher (who was my grandfather) originally from the Mansfield area of Victoria. He married Anne Francis Stubbs & came to Western Australia & ended up managing a large farm in Broome Hill south of Perth. I believe his father was sent to Tasmania from York possibably a convict & ended up deserting his family. The trail has gone cold as my father passed away & never knew anything. Donald & Anne's family consisted of 7 children. I would appreciate any help. Thanks Toni Nee Usher
