Hi, Syljun, there is a possible for Phoebe, but as for the others no luck, the Phoebe is:-
Phoebe Thomas, grave no. H1236 burial 2-3-1942. I only have the records for Barry cem. so cannot help with porthkerry, I believe the church only opens on a sunday now but not certain, but they still have burials there up to present day, how you contact the vicar I don't know, its a shame I did't have the info a few months ago as I have a caravan a hundred yards away from the church but due to illness am unable to get down there at the moment, All the best, Ken. p.s. I don't think its relevant but there is a Lewis Rees Thomas grave No. H514 bur. 8-8-1946 & A Phoebe Thomas bur. 13-1-1956 grave No. S279.
