Hi Charlotte, Researching traveller heritage can offer a minefield of difficulties, and you may not find all the answers. Not trusting authority, often with good reason, they lied or refused to give information. Many had aliases and often wanted to blend in with the locals. In Wales some took Welsh names like Scamps becoming Williams. Boswell also used Lock, and from my research birth registrations where the mother was a Boswell, they used Boss, Bass and Voss, as there was a stigma. I have 8% DNA that could be Romany, but reaching 1820 there is still no link. When you say Boswell fourth cousins, that would be five generations ago. Start with what you know and then work backwards, and fill your tree as much as possible. By having a fuller tree, when you hit a brick wall as many do, you might then find a different path. And don’t trust other people’s trees. If you cannot find specific information ask on Rootschat.
