Well I have researched (very briefly) the Exalls for a friend. The Withington George was my friend's great grandfather. His father was George b Weston Beggard and his father was John Exall. I have a tree and the wives tree. The reason for doing this was that one Albert Ernest Exall (son of the Withington George) was killed at Vimy Ridge in 1917 and I recently photographed the war grave for my friend who lives in Wales. If I can be of further help (or you can for me) please contact/post
