Not sure if this is of any help to you but in my family (Wraight,s) in Kent none were as far as I know direct descendant's of Gypsies, however my grandfather was married to a Pope whom I suspect may have been Gypsies.
My Grandfather and father and as far as I know quite a few Wraight,s were totally fluent in Romany and in fact my Mom and Dad quite often spoke to each other in Romany, their knowledge came from frequent dealing,s with Gypsies through business which I am given to understand was fairly common in the Blean, Faversham, Ashford area.
My Grandmother Pope apparently come from a circus family and I think a lot of people would confirm that many circus performers of this era were gypsies.
Cheers
