Hi Darren,
I thought I had replied, sorry!
I'd love to see a photograph of Roberts' grave. Shall I pm you? It's interesting that you say there's a connection with David Jones. I have a copy of a memorial card in rememberance of David Jones that I could send you if you're interested, and a photograph of Caergai.
I've always thought family history can be slightly addictive.
I'll have a look for your information on the LDS site, I admit I haven't really used it for family trees in the past. My trees are on ancestry and GenesReunited.
Thank you for the information regarding Evan and Sarah. Just to add to what I've already told you - Rev. Robert ap Evan's father was Rev. Evan Foulk who I believe married an Irish woman, possibly. I don't have her name though
And that's about as far as I have got, well, the bits that I'm pretty sure about.
Lisa
