My grandmother was a drewsteignton Mardon married to John Patterson of Axminster. In the 1930's some Mardon cousins called on my parents. They were on their way to Dorchester. I believe he was a cinema manager there. There may have been some mention of market gardening but I am not sure about that. Many years later I heard of a Dorchester Mardon who was a Chartered Surveyor but I do not know if he was related. Jim Swain.
