From a series of booklets about the lake by Edgar Harlan Wilcomb - "Winnipesaukee Lake Country Gleanings: The Lakeport Cleft and Great Prehistoric Dam" - Wilcomb Printers - Worcester, MA - 1923
Here's the map that was provided with the article that I enhanced a bit. Note how New Durham really lost out on a lot of lakefront property!
Snowbird: Thanks for that wonderful recommendation. "The Gunstock Parish" is a treasure.
