Hello Yvonne I had a look at http://www.familysearch.org/Eng/Search/frameset_search.asp?PAGE=af/search_AF .asp&clear_form=true and discovered a part of your Newitt line of South Australia. The site records your James Newitt (b.c1845 England died 21 Sept 1897 SA) and his brother John (b.c1840 England died 29/4/1916 SA), and his father Thomas who was born about 1814 in England and died 23/4/1873 in SA. You mentioned James's parent's were Thomas and Mary, however my Thomas (born 1796) and Mary (born 1802) had a son James who was born in 1832 in Chatteris Cambridgeshire UK. Therefore that rules out this particular branch. Regards Alan
