This is all fascinating. My great grandfather Lewis Henry Smith came over from Detroit, USA, WITH Singer Sewing machines, when the factory was opened. He and his wife and five daughters lived in Helensburgh.
I was born in Helensburgh in 1934 - I can remember air raids, although H'burgh was not greatly affected by dropped bombs - only one fell off the pier - but the noise was horrendous, all the time, and we could see Clydebank, Greenock, all the shipyards, burning.
