Have just found your site. I have a Robert ONN in my family tree, he is my GG Grandfather. Robert was transported to Van Diemans Land ( Tasmania) in 1843. He was a native of Newcastle upon Tyne, but had been brought up in Spalding in Lincolnshire. His father's name was Thomas and his mother's name Margaret. He had a sister Margaret and a brother Edmund. ONN is a well know surname in Lincolnshire.
