The first monument is in Blundeston St Mary Suffolk, with the same arms for Clement Kitchingman, Rector, impaled with those of Mary Howard. He was from Norwich but his family originated in Shadwell near Leeds. I do not have any documentary link to the Kitchingmans from the North Riding, though I suspect they are related.

Dorothy Blyford (nee Kitchingman) was born in Halifax but descended from a branch of the Kitchingman family from Thirkleby in the North Riding. I have a blurry photograph but the description in British History Online reads:
