I came across your website about Thornhill Square and saw a little mention about the Huntingdon Street bombs in 1940. My great great grandmother, great grand aunt & either my great great or great great great great grandfather (we're still working on that part of the family tree) as well as various other members of my family/family friends also died. I'm working on the whole list – but I have heard stories of the bombing from my granddad who heard them from my great grandmother. I can definitely say one of the houses was 55 Huntingdon Street and that my great great Grandmother Annie Hislop did survive only to die later that day (the story goes that the ambulance people nearly dropped her and she died of shock – not too sure if that's true but that's how the family story goes). And unfortunately for my Hislop family members – they had been moved from Lyon Street (in the only house left standing!) to Huntingdon Street – persuaded by my great grand Aunt Emily McEllhatton (nee Hislop)! The family left stayed in Islington (and merged with the Busbys on the marriage of my great grandmother) and the Barnsbury area in general until fairly recently. I could probably ask a bit more about the Huntingdon street bomb when I next see my granddad and uncle (who has the death certificates of some of those who perished).
I know residents of 55 & 56 were on the Islington Civilian Roll of Honour, and I think someone in 57 was on the list too but I don't remember seeing it when I was searching it. And I know for definite that 7 members of the Graham family, Nellie and Frank Howell, Annie M R Davies plus my great great grandparents Annie & Cornelius Hislop & great grandaunts Violet Hislop & Emily McEllhatton were the members of 55 who didn't survive – so if anyone recognises the story or names – they can check the commonwealth war graves commission. I don't mind if you put these up now, I have the general gist of the story and if I get anything extra from my grandfather or uncle when I go down to see them tomorrow, I will most definitely email you back with any extra details!
