Hi,
We too have casualties as a result of the Thom Street bombing. They were Elizabeth McQuade (maiden name Barbour ) widow of William McQuade and her son also called William. They both died as a result of enemy action on the 16th April 1941 at 5 Thom Street.
I agree, there is little about this raid but lots about those two or three weeks later. If you find any photos or other evidence, I'd love a copy. Likewise, I'm happy to share what I have.
