Mum's father was a bo'sun on board a cable-laying ship, going between England and Canada to lay and repair the telephone cables. He lived in Canada, but if the ship was going to stay in England for any amount of time, my grandmother and their two daughters would come over to Plymouth and the girls would go to school there. And that is where Mum and Dad met, at school.
In the 30's, Grandfather quit the cable ships and they all went back to Canada, permanently. Mum and Dad then became penfriends for several years.
In 1939 when war was announced, Dad wrote " There is going to be a war. If you will marry me, please come as soon as possible". That letter was carried on the very first air postal delivery service - I still have the commemorative envelope with the letter inside.
And yes , reader, she did marry him. Caught the first ship out of Halifax, Nova Scotia and sailed to Liverpool. Caught the train to Plymouth and they were married a month later, in October 1939. Totally devoted to each other for 60 years.
