Hi there you have a very similar story to my Arthur Devlin's line. My Grandmother told me that the Devlin surname should not be that but a McC something. She could not remember what her husbands father had told them. The year of birth for my Arthur would be around 1810- 1815. He deserted and went to the USA. My Arthur was married to Eliza McCarten. Had one son that we know about my direct line John Arthur Devlin born Ireland 1834. I wonder if we are related as the story is so very much alike.
