Traditionally, The Mennonite Game is the "game" played by two Mennonites when they meet each other to determine how they are related (because every Mennonite is related to every other Mennonite). It usually requires both people to have fairly good knowledge of their respective ancestry trees. However, there is the GRanDMA project by The California Mennonite Historical Society that attempts to keep a record of every Mennonite[1].
This project, The Mennonite Game, takes two people and finds how they are related through the GRanDMA project.
The Mennonite Game is meant for my friends, family, and myself.
