The name Bertram means "bright raven", from Germanic roots. The name meaning has quite a connection with the Ravenclaw house (bright as in witty, and raven as in Ravenclaw), which could lead to speculation that Bertram Aubrey was a Ravenclaw.
The name Aubrey has multiple meanings. It can mean "noble and bright", "blond ruler" and "rules with elf wisdom". This could also connect him to Ravenclaw, being "bright".
