with respect to my two previous messages i have since realised that the John Henry Garton who i thought might have been my great, great grandad wasn't. Since looking at RootsWeb - BULLEY of Great Yarmouth i have discovered that he married a Harriet Hall Radford and not Jane McDowell.
There was another John Garton in Hull who married Jane McDowell in 1843 and it appears they had at least 3 children; William, Charlotte and Charles. William married Frances Simpson in in 1887 and my grandfather Arthur Garton was one of the children to that marriage.
I need to check the above details properly but just wanted to correct my previous error.
