I have a grandfather that lived in Minn...Arthur Potter/he married Addy James and had two children/Merle & Murno Potter/they divorced and he married second an Adeline(same name as first wife)and they had several children. I have just done this tree and have found it difficult to find any records so far.I just have to hit the right place.He was a secret in my mothers world and I was never told about him until she died.I would be glad to share anything with you if I have anything you can use.
