Wow Len that is wonderful service! I had found them on the 1841 census, and assumed that Charles (the son) and Catherine were married. I have been unable to find Evans birth, and so you have given me so much information. Thank you so much. Searching the census for later years only Evans appears, Charles (dad) dying, closely followed by his son Charles. You have given me so much to work with.
Best wishes and thanks again!
