I've always been told that the name originates from Prussia but like you with your Poland link I have found no proof of this. Its quite possible that it did in fact originate from France as taken from Cecil Powell's autobiography it says:-
I was born at Tonbridge in Kent, in the South of England, on the 5th December 1903. My father, Frank Powell, came of a family which had lived in the neighbourhood for some generations and my grandfather, Peter Powell, had established a gunsmith's business in the town which my father inherited. My mother, Elizabeth Caroline, née Bisacre, was the daughter of a schoolmaster, a Gloucestershire man of Huguenot descent, who had migrated from Wotton-under Edge to the small town of Southborough, two miles from Tonbridge, where he had set up a private school. I was the elder child of our family, my only sister, Phyllis, being three years the younger.
This would indicate that he must have known of some connection presumably prior to John who was born in 1778 in Gloucestershire.
