One can read more about the cult leader Ervil LeBaron in this online book:
Ervil had thirteen wives in their colony in Mexico. The family was associated with appliance repair businesses and car sales in Texas and various states. Many of the children born in the Mexico colony would not have birth certificates (possibly). He stood 6'8". He wrote a document from prison with a hit list. Many people on the list are said to have gone into hiding. His family lived in his colony in Mexico, and Texas, among other locations.
As suggested by another WS member in this thread, this type of scenario (or associations with this family) would be an excellent reason why a person like our UID would be in hiding or might have the need to use someone else's identity.
Is our UID a sister (or half sister) to Jacqueline Tarsa LeBaron?
