Hi Steve
I realise this is a long shot, but thought it worth asking.  My grandmother had Travellers in her ancestry - the Eastwoods, who started off in Sussex & then worked there way across to Maidstone/Dartford.  In 1867 John Eastwood married an Ann Jones in Bexley.  She was born any time between 1837 & 1841 - depending on which census you believe, & she consistently gave her place of birth as Bexley.  Her father's name was George.  This is all I've been able to find out, & have been through the 1841/51 census's for Bexley & Bexley Heath without finding them.  She & John had their first child in 1861.  Is this a family you've come across?
Many thanks
