Hi Barbara,
Your line fits in with my family information,
William Vaughan married Mary Ann Owen then she married again after his death to Albert or Alfred Nicholas and had about four more kids. William died in 1859 at 35yrs and is in Ruardean parish church buried with his parents.
If you look at some of the other threads on this message board about the vaughans you will find a lot of information there. I have a copy of William Henry's birth in 1857 ( his birth year varies from census to census, marriage cert etc!. Westbury on Severn is the main registration distrcit for most of his activity!
