Abercrombie might very well have discovered an entry for the child of Ann/Anna but the birthdate would be all wrong, and the name of the mother might have forced him to slam the lid down on Pandora’s Box and say nothing.
Could be. Either way, he sure did backtracked fast and shut his mouth on all fronts concerning little Barry.
