Just a thought and it is only speculation.
My grandmother was very into social service organizations through her church. I remember sometime in the late 50’s or early 60’s, 2 guys from Pakistan (East or West, cannot remember) were at her house for an extended stay.
She and my grandfather were sponsoring them for something. I think they were students. Memory is vague, I was in the 2nd grade or so.
Getting back to my point, I wonder is Stan the Man might have sponsored BO Sr or one of the other students? Might explain how BO Sr and Stanley Anne got so close so quickly.
You may be right in this approach.It is very possible.
