Thanks, Matthew ... I've disconnected Margaret as the wife and and mother of this particular family.
The notes do indicate that the mother of Richard Tydings-4 has not been identified. It also appears that there were two John Tydings, and the one connected as Richard's father is not the same as the one who was married to the unknown Margaret who died at the time of her son Richard's death.
Personally, I can't make heads or tails from the baptismal record.
