Jean, I am not sure myself about that but maybe through the LSD could help here. I live in Australia and have collated information just for myself and family. My father was Sydney Thomas Sinton born Newcastle 1905 to James Donald Sinton, son of George Sinton & Margaret Walker. I also have the information of Sarah Ellen Kent whose mother was Mary Balmer, my gggrandmother. My father had her eyes. If you have this information the first John Ingo was born in abt 1813, his mother's maiden name Ingo. Then Ingo was carried through from here.
