You may already have the answers to your March query, re
Capel Seion. There is a graveyard behind the chapel in the village of
Capel Seion nr. Aberystywth. Some of my family are buried there. Not all graves are still readable, but you may find someone who can look for you. Try the Ceredigion Archives,
archives@ceredigion.gov.uk - also the National Library of
Wales holds records of burials in
Capel Seion from 1847-1962. They have a website but you would have to contact them to get them to do a look up for you.
