Hi and Welcome to Rootschat
I found this a little hard to search for you. I couldnt find either Joseph or Enos Mills christening but did find them on the census.
It would seem that Joseph was born in 1802 and Enos or Enas on some pages was born in 1808.
I did find an interesting thing about Joseph
Joseph married Ann Fry on 16th December 1834 at Westbury.
On the 1841 census I could not find Joseph but did find Ann still in
Westbury at Gills Close, with 3 children John 6, Sarah, 4, and William 2
Ann is 30.
Then on the 1851 census Ann is classed as the Head of the family and
marked as a Widow. She has John and Sarah and a Elizabeth but no William.
John is a worker in a Cloth Factory
I also looked for Joseph on the 1851 census and found him, bearing in mind
Ann states she is a widow. He is a lodger at Albion Yard, Newtown, Montgomeryshire, Wales. He is a Weaver and classed as being born in Westbury, Wilts in 1802. So must be him. He is down as still being married?? Intrigue lol.
I think the John Mills you say is the father could possible this marriage
John Mills married Hannah Miles on 27th September 1798 at Newton Tony.
This needs checking again.
I did also see this about Enos.
Enas Mills born 1808 Westbury died Oct 1868 aged 60 years.
Hope this helps with your research
