What State? Years? Children? Any more details?

I Understand that Samual Irvin and Sarah Ablaster may have arrived in Perth. And a marrage date of 1868. There children, Charles, James, Jane, May, Robert, Sarah, Samuel, Mary, William, David Lesley.
David Lesley married Christina Mary lake and their children are Ronald 1915-1987, Robert 1917-1942, Mavis 1919, George 1921-1943, Olive 1925, David 1934-1995.

Ok, thanks for the extra details. Now goto the RootsChat.com - General - Emigrants - Emigrants to Australia chilboard. Read the links for WA genealogy. Post a lookup request for your IRVIN/ABLASTER family. They'll be on passenger lists somewhere. I've found my DENNER/PINE ancestors arriving from Plymouth at this free to lookup website. Bound for South Australia.

Hope this helps. Any more questions, just ask. Oh, and lots of rootschatters have the bdm indexes for all States of Australia.

TIP: FamilyTreeCircles site works best if you type the surnames you are researching at the bottom of each journal, e.g. IRVIN, ABLASTER.
