Hello Jane

I know it's a while since your posting, but thought that I should clarify. I assume that you are looking for the burial of Phoebe Harries, nee Davies, with husband John Harries? (Rather than "Phoebe
Harries nee Davies died 22 mar 1871 Bwlch farm ,Mydrim. Her husband was John Davies." from your post).
I found the death of Phoebe Harries, age 41, in 1871 (Carmarthen 11a 534)
Best Wishes
Morgan
