I have read that in the NE area of Aberdeen, families used the "tee-name" pattern when naming their children. Can someone tell me what that system is? My ancestor's name was Mary Jane Anderson. She was her mother's first child and I believe was illigitimate. Her mother is one of 13 children (5 sisters) and neither HER mother or any of her siblings were named Mary. Her third sister is named Jane.
What was the "tee-name" system?
