Kay-Barr on Family Tree Circles

John Perkins, plasterer, of England; his son, Richard Perkins (born abt. 1844), married 1866 to Mary Ann Keeling, in Kensington, Middlesex, England. Who was Richard's mother? When were his parents born, married, died & where are they buried? I've not been able to find any records for them, my gg-grandparents.
