First, apologies Redrock, I did get my census details out by 10 years in an earlier contribution to this thread....I was working from memory rather than hard copy! I have now subscribed to an on-line source for the UK census so can check my details now!
An interesting question about which Samuel was the criminal, and which the father of Woodhouse junior.
I have seen the parish records and confirm that a Samuel Varney was christened in Belper on August 4th 1799, son of Woodhouse and Elizabeth. This would make him around the same age as the Samuel Varney who died in Rotherham, although perhaps not exactly in line with the death certificate. There is evidence from records of the Belper Poor Law Union that they were aware of a Samuel Varney being ill and dieing in Rotherham. There are instructions to bring the family back to the Workhouse, as would have been the law at the time for the descendent's of men born in the parish and his family who sought parish relief. There are no Varney's listed at the workhouse in the 1841 Census, but Mary Varney appears to be lodging with her 3 young daughters in a house in Swinney Lane, which is close to where other Varney's were living. She has employment in the local cotton mill.
A Samuel Varney married an Ann Jackson at the parish church in Duffield around 1821. I have not seen the microfiche record of this yet, but hope to confirm this when I next visit the Derbyshire record office. Woodhouse junior was christened on Jan 16th 1824, son of Samuel and Anne Varney, and I have seen this record. There is an Anne Varney buried in Belper in the 1830s, but I want to check the exact date and details. So it is possible for Samuel to re marry and have a second family.
I am not aware at present of any other Varney's in Belper that could fit the dates for the Rotherham death. The eldest of Mary's daughters was born outside Derbyshire, the two youngest in the county, according to the 1841 Census, so it is possible she married in Belper. Another point to check!
I am not sure Ruthy about Woodhouse junior having a sister called Elizabeth. I didn't make a record of any Elizabeth christened in Belper in 1826 when I was going through the parish records, but it is so easy to miss things when trying to read those microfiches! Can you give me any details?....I will add this to my check list. A possible candidate for Elizabeth is the one born about 1830 to Thomas Varney. He was the second (surviving) son of Woodhouse, so this Elizabeth was the grand daughter of Woodhouse senior. She can be seen in the 1841 Census living in Belper, and was employed in the local cotton mill, so could have got employed in the same industry as a factory hand....
You are quite right Rocky, I cannot be sure which Samuel Varney was the one imprisoned. Firstly, there is the possibility that he never returned to Belper after release. Looking back over what records I have collected so far, their are two possibilities other than Woodhouse senior's son. One died and was buried in Belper in 1841 (before the census), but he was 77 so the least likely candidate. The Samuel Varney you found in the 1851 census, born in 1786 is possible. He also appears in the 1841 census, although his entry seems to have missed transcription.
He has a wife Isabella in 1841, so is unlikely to have been the person who assaulted his wife, Anne, unless he had remarried.
The Samuel sentenced in 1826, although described as a labourer in the Wirksworth record, is described as a nailor in the pop up note attached to the Derby assize record. At this time the township of Belper was still in the parish of Duffield, which is close by....the registration district was not invented until 1837. All the census records you saw for 1851 are definitely for Varney's living in Belper.....most of the addresses are still identifiable to this day, and the terraced cottages they lived in. Duffield is declared as a sub registration district of Belper on the 1851 Census transcript....I think that this just means that Duffield held a record book where their citizens could record births, marriages and deaths which were later transferred to the main one at Belper.
Unless I can find a record from contemporary sources giving the age of the Samuel sentenced in 1826, I guess it won't be possible to definitely identify which one it is.
