Excuse me, but where did "William" come from? In the 1851 census he is called Glanvill Payne, and in the 1871 census he is called Glanvill Pain. And the 1851 census shows more than 3 children: there is Mary Ann age 10, Glanvill age 8, Joseph age 5, and Ruth age 2. Or have I got the wrong family? In 1871 only Joseph is still at home, age 24 and a miner, but there is also a grandson called William H Cotton, age 14.
Is this the right family?
