Hi Roger,
I assume your ancestor was:
James McNab
1864–1941
Birth 1864 • Queensland
Death 29 SEP 1941 • Queensland
I am on Ancestry.com and Im touch with other relatives in Brisbane...Rebecca who is related on James brother Alexander's side...her Great Grandfather..
My Great Grandfather was Thomas McNab, my mothers Grandfather, he was the youngest of the children..born in 1839 in Blair Atholl Perthshire.
I am also in touch with other McNabs in the UK..where I was born...I know another cousin there has his family tree online too and he will be very interested in your information...
I have traced another cousin to Canada...
Do you belong to any other sites? I will add all your information to my tree, and also let the others know...how nice to be in touch with a McNab...so proud of my Scottish side.
Cheers
Andrea
