The email was sent by Olov Bygren. He was studying the population records of an obscure town in northern Sweden, Overkalix. What made these records unique was their detail. They recorded births and deaths over hundreds of years, but they also had accurate details of the harvests. More significantly, Overkalix's isolated location on the Arctic Circle meant that it was particularly vulnerable to famine.
In the 19th century, this was a very isolated area, they could not have help from outside. As it was so poor, they really had a hard time when there was a famine, and they really had a good, good time when the, the harvests were good.
Bygren appeared to be seeing links between generations that confounded his expectations.
I sent Marcus Pembrey an email telling him that we had some, some data, which could interest him.
I was terribly excited to get this completely out of the blue, and for the first time, it seemed that there were some data that we could then start to explore, so that was the beginning of our collaboration.
