The Enfield Shaker Museum, in Enfield, N.H., memorializes a community of Shakers, a mostly 19th Century New England Protestant cult dedicated to, among other things, simplicity and pacifism. At it height the  Enfield community had some 300 members. They built lovely furniture and wood and brick buildings. While they took in many orphans, children from poor families and some converts, that wasn't enough to offset a major impediment to their efforts to achieve long-term growth: Sex wasn't allowed. The cult died out by the early 20th Century.
