CC3 question

EDIT: MY SPOILER TYPING ISNT WORKING DONT LOOK!!!!!

Hello question about Lydia >!so did she name her kids Gavin and Brennon bc she’s heard stories from other worlds? Probably like word of mouth from old books that used to be accessible? Or from people who traveled to Midgard so long ago? (if I’m not getting the world confused just finished TOG so my brain is scrambled) lol!> please help!
