HELLO EVERYONE!! This is my first time on here..actually didn't know about it... I am Christian Garretts former mom in law and I can answer your questions.
NO, HE IS NOT KIN TO ANY OTHER GARRETTS THAT YOU KNOW. His name is Stone by birth, he was adopted by his step dad in later years, hence the Garrett name.
He was only UPC for a very short time and went kicking and screaming into it then. He only did it because the church he was pastoring at the time was UPC.
