Thanks. What to you think about mapping them as place=farm? Aren't mennonite colonies farms?

Wouldn't  be helpful to also tag them with religion=christian + denomination=mennonite ? These tags would be needed to find mennonite features based on them and not in names or other attributes.

Anyways, are you sure mennonite colonies want/like to be mapped in public databases like OSM or they would prefer to not, and keep lower profile to be easier to follow their religious precepts?
