Just came across your post. I am married to a Guinen with all the same family members names you mentioned...and similar family stories. I did find many misspelling in the names when searching and 'found' ancestors almost by accident. I believe my husband may be related to your father. I have not heard of John's whereabouts for some time, last I heard he was in New Hampshire and moved to Florida. If this is the same John Guinen, please contact me for further updates. Do you have
any brothers and sisters? What state are you from?
