Interesting!
Do you reckon Joseph may have changed jobs a few times and may just have been a shoemaker before he was a schoolmaster etc etc? Or is he the Joseph Blanch living in Paganhill Stroud who is a millwright by 1861- and married!
Come on ancestry, get 1851 back up and running! im thinking the 1841 Joseph - possibly Cornelius' brother, according to IGI, they were both sons of Samuel and Sohia Blanch.
This is getting very interesting, I wonder where Jacobs name came from, id love to find a Jacob Blanch!
