Well, when I looked back I realise they (or she) aren't in my direct line, but what I have is this:
In Essex I have Richard PORTER born 1776, who married Sarah CABLE (or CABELL) on 11 May 1806 at Christchurch, Latchingdon Cum Snoreham.
Their children were Mary Ann, James and William (may have been more)
Mary Ann married Samuel George SMITH 23 Sept. 1833 at Latchingdon Cum Snoreham, Essex.
James married Mary BALLS on 28 Sep. 1838. Mary lived in Snoreham. Her father was James BALLS, occupation – labourer. She was 26 and James was also 26. Witnesses to their wedding were Isaac Bonds (could be Bones) and Sarah Hart.
William married Eliza ABRAMS on 17 Oct. 1836 at Latchingdon Cum Snoreham, Essex.
Do you have any of these in your tree?
I'm sure I've seen BALL or BALLS on the census for Show people/travellers.
