Below is a photo of Elizabeth (Bessie) Scott Graham's family in 1917. Duncan Scott was her grandfather, and Maggie Scott her mother. They lived in Dublin, fairly near to Kilkeel, until 1940, when they followed their daughter to England on retiring.
Whereas (I believe) 10 of Maggie's 11 children survived to adulthood, Bessie was not so fortunate. Only 2 of her 10 children outlived her. Three of four twins died very young (the only survivor was my father, the baby in the photo), another daughter died very young, a son died at 9, another in his twenties, and two more in their thirties, far away in Africa. And yet Bessie still had 10 grandchildren, after all that...
At the time of the photo, most of the tragedy is still ahead. She's just lost a twin, and two children previously - and worse is to come - but already she looks terribly sad.
It seems there was a tendency for twins among Maggie's children, and I wonder if this came from Duncan and his wife Margaret, or from the Graham side? (Having asked the question, I see that Duncan's son James was a twin).
