Anthony: I don't have the exact places for you to start checking in the USA but I have corresponded with someone who may be able to help you. His concentration is IVES and the Civil War (War between the States)His name is Ken Ives, kenives99@aol.com. He has been very helpful in  hunts for ancestors and I am pretty confident he could tell you what internet sites to visit to start your research. Please feel free to mention I suggested you contact him. Barbara Ives Perez PS, yes, I am a Maxwell also, unfortunately, that line is still very much a mystery before 1840.
