Misreported here as The Divine Order of the Royal Arms of the Great Seal but actually known as Divine Order of the Royal Arms of the Great Eleven this story is notable not just for its sensationalism but for the claim by the Auckland star that the report comes from their own correspondent.
WEIRD RELIGIOUS CULT.
Auckland Star, Volume LX, Issue 262, 5 November 1929, Page 18
This case of cult activity seems to have went largely unreported and buried by time.
“Divine Order of the Royal Arms of the Great Eleven” brings up only 63 hits on google while “Blackburn Cult” (as the groups Wikipedia entry styles them) brings up only 372 hits, most of them not actually related to the Cult.
