I realize that the post to which I am responding is rather old, but if you are still looking for information about Burt Hallock and Linnea Wanberg, I may be able to help. At least one of their 3 sons was born Connecticut. Linnea Wanberg was born in Sweden and naturalized at Vergennes Vermont. Since one of the sons living in Oregon, is an uncle by marriage and a second cousin once removed, I feel I should call him and get his permission before I give out much more information. The other son was living in Vermont as of the last information I had. The oldest son, Kenneth passed away in 1998.
