With variations of spelling (Excell, Exell, Axell) this name seems to occur frequently in the Marden and Goudhurst area in the 18th and 19th centuries.
My great, great grandmother was Mary Exell, who was born at Marden around 1812-14, although I have not so far managed to establish who her parents were. She married Thomas Roberts at Goudhurst in 1830. She died at Maidstone in 1885, and was buried at Marden.
Any links with your family?
