Robert Plant's Romani roots? 

I see that there are some information about Plant having some Romani roots. As far as I know, however, Plant said "my mother was a gypsy", where "gypsy" could've meant "a traveller" or a "a hippie" - in terms of a lifestyle, not ethnicity. He could've meant some Itinerant groups in Europe like for instance the Irish Travellers or maybe some Scottish Gypsy and Traveller groups. I know Robert Plant is from the UK, and I've heard that British people usually don't use the word "gypsy" when speaking about Romani people, but they use it when speaking about people who lead itinerant life. Any conformation that Plant used it in terms of his Romani ethnic origin?
