Thanks for your reply. Anything is possible with spellings of names. The family is listed as Mcgranahan on the shipping list I have, and they could have just kept using it, lots of names got changed when people arrived in Australia, quite often through misspellings.
Do your friends have any family history of any of their family migrating. ?
The McGranahans were farming in Victoria near a small town called Ballan. Unfortunately Patrick died 9 years after arriving of diptheria. In the meantime though they had another 5 children.
Catherine who was 1 when they migrated married Henry Charles Busch in Brisbane, Qld. He was brought up in the Goldfields of Central Victoria and probably met Catherine, who was known as Effie in Victoria, and she came north to marry him. He was a master at Ipswich Grammar School, near Brisbane. He drowned in the Brisbane River age 31 in 1889. Effie took the children (5) to Western Australia.
Henry and Effie's daughter, Caroline Ethel Busch, was my late husband's grandmother.
That's a bit of OZ history for you. Any information would be much appreciated.
