Hi
Looks like it's all coming together well from the other posts.
There are some Worcestershire Neath(a)ways on the IGI, but Mary Ann said her place of birth was Pershore Holy Cross on the 1881 census and that place isn’t on the IGI for the period you want. I guess that is the reason you haven’t found Mary Ann’s baptism. I’ll try to do a lookup next week.
I’ve only had a few minutes to look at records today. From the Worcs Marriage Index at the History Centre I have scribbled down that a James Richardson married Hannah Boulton on December 24 1824 at St Helens Worcester. When I was at the County Hall branch of the Record Office, I looked at part of the Kempsey parish register on film. Your Thomas named his eldest son Thomas Boulter Richardson (well that’s how I read it!) So I’ll just need to check whether the name was Boulton or Boulter.
Fitting a bit more of the jigsaw puzzle together. Two of James Richardson’s sons married sisters at Kempsey on the same day. George aged 26 of Kempsey married Sarah Ferriman of Claines, on 20th October 1863 the same day as his brother Henry aged 23 of Kempsey married Anne Ferriman of Pershore, Holy Cross.(!) George Ferriman was their father. One of their witnesses was Thomas Richardson and he signed his name. So, hopefully that signature will look like the one in Whittington PR when he married Mary Neath(a)way, from Pershore, Holy Cross, in 1857.
When father James Richardson married Hannah in 1824, he would have been aged about 20, as he was baptised at Leigh with Bransford in 1804, as previously mentioned.
