re: Young Sheldon Finale'

Without rewatching the scene, I believe her name was Valerie, but I could be wrong. It wasn't anyone that was ever shown on camera or mentioned otherwise. This was the first time that person would've come up.

Speaking of which.... 7 seasons and we never once got to see Mary's other two siblings Charlene and Stumpy ("Although if he'd listened to me about that wood chipper, we'd still be calling him Edward." - Mary BBT)
