G'day Leslie
firstly I really do wish you good luck with your search. I can't offer you too much, but if I were you I would stick to your original name, although the middle English names of Wigeyn, Wygan, from the old French Breton names of Uuicon, and Guegon might prove helpful further down your search.
If of any help, my family are huge in the oxford/woodstock area, though I was reared near Wigan in Lancashire!!!!
Best wishes
