I can. If your grandmother is a tall red-head who lived in Queensland, she and I used to go crocodile hunting together. Each afternoon we'd go to a tin-roofed cantina to drink beer. She'd dance on a table top with a rose between her teeth and the other crocodile hunters would make paper airplanes out of Australian dollar bills and toss them at her feet. She married Ralph Cleasby. I introduced them one night, and the sparks flew. He and I had been in the RAAF together.
Your 3rd great grandfather came here courtesy of HM government on board the HMS Retribution, with 500 other convicts, in 1837. He did well after he served his sentence. At one point he had 12,000 sheep on his station.
If that isn't you, then post again, with the name, birth date (as 01 April 1888, not 04/01/88), birth place (town, county, state/province, country) and spouse's name of someone in your family born before 1920 - the more before 1920 the better - and I'll see what I can do.
