I've twice tried to post this on the tragedeigh Facebook group and haven't been approved because they think I'm bulls***tting, but I have had confirmation on this from several people who lived in my city at the time of this.
My mom taught at a school in the 80s where there was 2 siblings, one named Hallelujahthemessiahiscoming, and Repentorburnforever.
I thought my mom was BSing for years until my coworker told me my mom was a teacher at her school when she was a student in the 80s.i asked my coworker about this, and she said yes, she was a little older than those kids but remembered them because they were in swimming classes at the local pool she was a lifeguard at. She told me her younger brother knew them and said at least one of them got into [illegal substances] later.
