We tend to call it step dancing in the south of England. The Devon version is taught every year at the Dartmoor Folk Festival. There are also people learning Sussex step dancing whom I can put you in touch with. As others have said, this is a separate tradition from Morris clog. There are quite a number of gypsies who are very good at step dancing, namely the Wests and Buckleys in Cambridgeshire and the Orchards in Devon.

Good luck
