Hello Tom and CereUK
Boy this is very confusing indeed...
I am descended from the marriage of Nathaniel Josiah and Ann Reynolds via his daughter Elizabeth.
That marriage was was on 22nd September 1864 in Wribbenhall, Worcestershire. I have the marriage entry records for that. Their marriage parented 11 children. Their life must have been a hard one. Nathaniel working on the railways as it expanded throughout the UK. We see by the places the children were born in that they lived in Railway huts and pubs along the way and they moved from place to place with the railways expansion.
NB: There were certainly a lot of people around at that time with the Pinnegar surname or variants of it. Confused even more by there being several Nathaniel's and Josiah's.
I realise that Nathaniel was married before his marriage to Ann (Reynolds not Spencer). As you rightly says Tom; he was married to Mary Fawcett in Kendal, Westmorland in 1846 - although I have no information on Mary Fawcett's birth or death. Just a note from an old relative that she was born and died in Kendal. I have no proof of this. That marriage parented two children: Sarah Ann (1866 Bentley) and Edward (1855 in Ulverston)
NB: It is interesting that if you look on a map at the route of where the children where born there is a definite railway line link between them and if you do it on Google maps and put them in date order the line is quite definite indeed.
What I cannot see or find out is when Mary Fawcett died and when - if he did - marry again before his marriage to Ann in 1864.
If, as you suggest, he married Eliza in 1863 - the timing and the place names of the marriages (Dursley) don't seem to make sense. Although there was a railway there and it is all connected down the same line. I just cannot find how Eliza fits into his life in just one or two years.
Forgive all the ramblings - I like to try and look at the person - the man - and Nathaniel Josiah Pinnegar certainly had an eventful life with his descendants many and varied and all over the country and in many other continents too I should imagine.
