Andrew Wilkie, Free Settler “Mangerton” 1852 and Isabella Wilkie, Free Settler “Mangerton” 1852 are on Geni with some children who I don't think are theirs.
Andrew and Isabella arrived in Australia in 1852 and as far as I can see remained here till they died
According to various internet trees these 3 children were born in Scotland after they arrived in Australia
What sources connect these 3 children as his children?
