Actually I live in British Columbia, but thats okay. Charles and George were brothers but I'm not familiar with this William. I have a few William's but none that I have enough info on to match with your info.
The family info I have gives: Jesse Deeprose m.1st Mary Ann Sargent. Children: Charles,Jesse,Edwin, George and Isabel Jesse and Isabel stayed in England. Edwin either left home as a young man or died in his early teens. He was never mentioned by my g-grandfather when he talked of his family.
Jesse Deeprose m. 2nd Mary Ann ____ (Offen) a widow with two daughters. There were two children from this marriage, Alfred and Ella.None of these four children were mentioned by George even though he was living in the household when his father remarried and the youngest two were born.
Most of my info is from direct family contact and Sussex county records so far.
I would be happy to exchange further info on this family if you would like to contact me privately.
