This is a fascinating bit of history. Derry was an early convert to Mormonism who emigrated from England to Utah, became disgusted with polygamy and what he saw as an abusive system of tithing and church governance, and returned to the American Midwest, where he joined the RLDS church and became a leader and missionary in that denomination. Like The Giant Joshua, it’s odd to read something that is so clearly “a pioneer story” but isn’t uniformly positive.
