Sorry, I suspected the spelling may well have been Hewitson when I couldn't find any real fit under "Hewetson" ( I underlined the "I") in my reply to you, and I thought I'd found you the right one in 1861.
Your first sentence has me a little confused. I'd thought you wanted to know more about Henry and his family, but you mention 1828? Do you already have them so far back?
"Corn merchants" as the young George's father John Hewitson was in 1861 was, would, to me, seem to be providers of provisions and so qualify for membership of that Guild, don't you agree, though? I did think the 1861 census might have been helpful to you.
If I was on the right George, I suspect he probably thought of where he'd spent his early years, in Battersea, when filling out later censuses of his own. Many others have done that if parents etc. are no longer with them.
I'd found the one with John and Eliza, but rather discounted them, as less likely to reach membership of a London Guild and to have sufficient affluence to import a Benz car - a very expensive and "swish" thing to do.
Both Lavender Hill and Battersea could qualify as part of London, couldn't they?
Anyway, sorry not to have been helpful to you. Hope someone else can help you more.
