I've googled that and read the articles. I've yet to come across anything dealing with the preachers history and the church itself though.
The rumour is ( and this IS just a rumour)..
that one of the preachers from the church lived in that old house closest to the graveyard. I think the house is now gone but this must have happened recently. It was abandoned and may have been tore down by the owner of the land that it sat on. Anyway ..the preacher may have been mentally ill or some sort of problem as he supposedly killed himself in that house. Another rumour is that he was involved in some satanic like practices and that these practices were occuring at the church. Who knows. Like you I cannot locate any factual history. Anyone know some facts ??
