Sorry about that. My personal knowledge of the works is that they were handed down through the family, last owner was a 95 year old, now dec. She had noted on the back of portrait that it was "Harry Newton, son of Captain Newton's second marriage". She received them from her mother who was given the paintings by Sidney and Henrietta Rodman, who had no relatives in Australia. The Rodmans had brought the paintings to Australia from England. They were always referred to as "the two uncles", with a connection to John Newton of Amazing Grace fame (but no resemblance to him from the only portrait that I've seen on the web), by well known portraitist (assumed to be English) and of some value. A family genealogist thoroughly researched the Rodmans back through Sidney Rodman's mother Sarah Jane Newton's line. Sarah Jane was dau of Thomas a Wesleyan minister and Elizabeth (Reeve) Newton, marr in Wiltshire in 1817. Sarah Jane was a painter and her will gave her son and executor (Sidney Rodman) option of buying paintings and prints. There is no mention in her father's will of such things.
My interest is that I'm currently custodian of the art works and hoping to discover their identity, as far as value is concerned that's up to the family. There is no visible signature on either portrait, but perhaps they've been re framed at some stage in their life. They haven't been taken out of their frames as I feel this should be performed by an expert.
I will try to reduce size of portrait/s to submit. Sorry for being inept, but I'm a learner (very slow at times). Marg.
