I am not "stranded" in Scotland either, Newist, though I was born in the south of England, where all my ancestors lived as far back as I can trace (1600 or so) My aunts, uncles, cousins, and cousins' families still live in the south - those of them who still survive. I have just heard that a 94 year-old aunt has died. It is a long way to a family wedding or funeral, but I am in contact with many of my numerous cousins.
But I have been here since I was 16, when my parents were moved up here, like it or not, with my father's job. When we lived in Fife I went to school there and made friends, and was never treated with the hatred that mythology says the Scots feel for the English. My further education was in Edinburgh, and here I made more friends, and met my husband, and was assimilated into his family.
My children are Scottish, but all three have met English partners,and two of them are settled with those partners here, but keep close ties with their English families. The third lives in the south, is close to her husband's family, but keeps her ties with us up here.
There is not an iron curtain across the border. Families have links in both directions (and further afield) Businesses and individuals come and go freely and I am sure will continue to do so whatever the outcome of the referendum.
