I don't know a lot more about him. He was my father's eldest brother. One of two who emigrated to the USA in 1901 after the census dates. Didn't think he had ever married, also I had a quick look for a marriage to a Cath or a birth of baby Emily, but found nothing. Of course he may well have fathered a child and still be the George you found.
His baptised name was George Herbert QUILLIAM.
He sailed in May 1901 to Philadelphia, the ship's manifest stating last residential address as Peel, although all of dad's family were in Foxdale prior to that.
Thank you for your help.
