Complicated one here.
When my DD married 20 years ago, she wanted sweet peas in her bouquet, but May was too early for them. So early in the year I put something in the parish mag asking if anyone could grow her some in time. A lovely old gentleman offered to do this, and did indeed come up with beautiful sweet peas for the wedding.
Here's the coincidence ... later someone kindly did my ancestry for me and it turned out that this man was distantly related to us, and thus of course to the bride. We were incomers to the village and had no idea that we were related to several local people, including a tenor in the choir I run, whom I had known for years!
