LOL! No idea where my brain was going with "rocket person", but clearly it didn't go "right" as I intended. :)
For Beatrice, I know that her father's last name was Davey, but her mother remarried to a Gill, so that is why you will see Beatrice and her siblings listed as Gill from time to time.
So believe it or not, no mystery on that one for a change. :)
