I didn’t watch the show, but here’s what alert viewer TLCBKWORD@aol.com knows about the series:
"Thelma was an adult child living with her father. Most of the time she was trying to get the preacher (Clifton Davis) to fall in love with her (which eventually happened and they married) The stand in moms were the two sisters."
