Yes, I would be happy to have your email address. I don't know the Tjerslands in this country. We live in CT.
Arne Tjersland has done some geneological work and might know more about the Tjerslands who ended up in Washington. I do not have Arne's address at present. He is a former chief of police in Flekkefjord. He is a tall, friendly man with a twinkle in his eye.
My wife, daughter, and I are hoping to visit them this summer.
