Family tree

I met my husband in the 1970s in Newcastle-on-Tyne, where we were students. I was born and raised in Oxfordshire and he was born and raised in the west of Scotland. Many years later he started to research his family tree, branches of which are spread over many Scottish and English regions and States in America. One summer some American cousins came to visit. After staying a few days with us in Yorkshire we drove them to visit another distant cousin in Cheshire, a woman that my husband had never met, but whose name was recorded on the family tree. It transpired that she was born and educated in the same, small town as myself, and being as she is the same age as me I asked her to name a few of her friends there, thinking that we might have known some people in common. The first person she named was a boy she had gone out with - I had gone out with him too. Then she said that her cousin was at the same school as me, but as she was a year older I probably would not have known her. But I was in a year group one year ahead of my age, and the cousin was actually in my form group. I was at school with my husband's distant cousin, her name was on the family tree, despite our families being sited at different ends of the country.
