Hi,
Re Churches in Belper no marriages took place at the Chapelery of St. John, St. Peter’s was not built until 1824/5
So many B M D’s took place in Duffield.
Many people from Belper and Milford derbyshire moved to Lancashire in the 1840/50, mainly
Cotton Mill workers, they had been employed and Schooled by the Strutt family so most were able to read and write.
It was important to state where you were born, because if you became chargeable to say Ashton you were removed to the parish of your birth.
1851, note William gives birth year as 1826, and his Mother Mary Hall is living next door. However in the 1871 Census he gives a birth year of1824, this date matches with the following:-
Henry Hall = Mary Webster 8.4.1816 Duffield
John hall son of Henry Hall & Mary residence Milford occupation Bleacher
William Hall son of Henry & Mary. “. Milford. “. Labourer
Jane Hall son of Henry & Mary. “. Milford. “. Filer
All images are on ancestry, but note although Ancestry state St. Peter’s they actually took place at the Chapelary of St. John. Asked Ancestry many times to correct this!
The is connection to first page of the register, just to prove.
