Hi I am looking for any information on John Hanna who would be my 3 x great grandfather from Scotland. His wife was Sarah Rachael Boyd. Their daughter May Engstrom was my 2 x great grand mother who was married about 3 times according to her death certificate. She died in Rose Bay, NSW, Australia and was born in Glasgow, Scotland about 1860/61. Any information or guidance would be greatly appreciated. Thank you.
