Hello Roy As Pat has said, there was an Isaac Keeling with wife Sarah at Yate, Glos in 1851 although on that census he says he was born Poynton, Cheshire and it states he was blind. His age was 57 and a labourer and Sarah was age 56 born Thornbury, Glos. James Ford, his wife's son, was age 29 a coal miner was living with them. A daughter Rebecca Keeling age 17 and a nephew Luke Kendle age 13, also a coal miner were also living with Isaac and Sarah Keeling. Both Rebecca and Luke gave their parish of birth as Cromhall. Just 8 calls away on the Yate 1851 census was Jacob Keeling age 55 a coal miner born Northampton and his wife Edith age 58 born Greazley, Notts. Their children were William age 28, Celia age 20 and Hannah age 16 with a William White age 2. These were also all born at Cromhall, Glos. I cannot tell you whether Isaac and Jacob Keeling had a father called William but I see they both died in the Clifton Registration District of Bristol. Isaac aged 75 in the December quarter of 1868 and Jacob aged 81 in the March quarter of 1877. Hope this helps. Bernice
