If there is a Family History Center, near you, (LDS), they "should" have a
Birth, Marriage Death index for England and Wales.
For the birth of Samuel Jones,
Check the 4th Quarter of 1852 and the 1st of 1853.
It would have been Registered in Chrickhowell.
The same with the marriage, try the 4th Quarter 1875 and 1st of 1876.
If there are no Family History Centers near you, give me Samuel's wifes name
and I will try to get to the one in Los Angeles soon.
Hope this helps
