BIRTH: based on age recorded at marriage event and census
CENSUS: John's mother is given as Jemima Hole. His father was called William. But it seems as if John and George were not brothers but some family link seems likely as they both settled Firstly in Huish Champflower and then in Treborough. They were both iron miners.
Family say Jack Jefferies lived in Mountain Ash and was a trade unionist. Apparently received an award from the Queen.
