Hello, When did he arrive in the US?, Also did he marry in the UK or the US? Also his birthdate is ambiguous, the dates could be either, as Census birthyears are often incorrect, and sometimes individuals also didn't actually know their birthdate/year, It does sound strange but it did happen! When searching I would go either side of those years given as a precaution when searching for records.
His occupation may not give clues as to where he was from, this occupation was well known around the Country as Industrial employment overtook agricultural employment in England, to name a few: Wolverhampton and places in Sussex (Wealden Iron Industry) were associated with the Iron Industry Also it has to be said that 70% of all output came from South Wales (not England).
So unfortunately
you may be clutching at straws to focus completely on your ancestors occupation, as this employment was in constant demand.
Do you know anymore about his life when he arrived in the US? The 'paper trail clues' he may have left may yield answers for us with the resources searching in the UK
Kindest Regards Jen
