Robert Dewsberry had a business as a monumental mason in Ammanford. He married the daughter of another stonemason Evy Thomas, who died young from inhaling particles of stone chipped from gravestones. Before his death he moved to Llanelly where he was in business with his brother Tom, a coal merchant and colliery agent. He died suddenly at the age of 52. His funeral report describes him as “an ever genial and likeable personality who enjoyed the respect and esteem of a host of friends, amongst whom his death caused a profound shock”.
