According to the 1901 census John Dimmock was born c1861 at Pinxton, Derbyshire. It has not been possible to confirm this as no other census records or birth/marriage registration has as yet been found.
John married Eliza Ellis. Eliza was born August 2nd, 1860 at Pinxton, Derbyshire, the daughter of Ann Mills & John Ellis, a coal miner. Eliza had previously been married to Joseph Sanders, a coal miner, whom she married at just 16 years of age. Eliza & Joseph had a daughter Emma in 1877 who appears to have been raised as Emma Dimmock. It is assumed that Joseph died but no marriage certificate for Eliza & John Dimmock has yet been found to confirm her status.
John & Eliza had moved to Yorkshire by 1882 & at that time they were living at Methley, Yorks. When son John Charles was born in July 1882 his father registered the birth & interestingly gave his name as Charles rather than John Dimmock.
