- Diana - Williams late-mother. I think that if it were to be a girl, the first name (or the first middle name) would be Diana. Hands down!
- Elizabeth - William's grandmothers name and Catherine's middle name.
- Carole - Catherine's mothers name.
- Dorothy - Catherine's grandmothers name.
- Frances - Willams late-grandmothers name.
- Charles - Williams dads name.
- Philip - Williams grandpas name.
- Louis - One of Williams middle names.
- John - Williams mother's dads name.
- Henry - Williams brother name.
My Picks:For Girls, Diana, I think it's on everyones list of names. Elizabeth because it's Catherine's, Beatrice's, Lady Louise's, Anne's middle names.
For Boys, Henry, I think everyone either wants the child to be a red head, but I would perfer one of his middle names Henry. Philip because it's mostly every Royal guys middle name.
