[1] In 1953 he married Eleanor Mary Scheppens, nicknamed Nora, and their only child, a son called John, was born in 1957.
He was a major contributor to the knowledge of the European Chalcid fauna, especially the Pteromalidae, Mymaridae and the Eulophidae.
The research he conducted during his visits to Trinity College enabled him to make many important discoveries and as a result of the field work he conducted in Ireland, he was able to add many species of chalcid wasp to the list of those found in Ireland, some being new to science.
[2][1] However, he continued to work on entomology after retirement and was preparing a paper on the revision of the genus Torymus when he died, he refereed a paper for the Bulletin of the Irish Biogeographical Society just before he died and gave the authors invaluable advice, despite his failing health and hospitalisation.
