When I was younger, we always called it Cum bress
like your wife, but we were outsiders from Ohio.
The link about made it seem like Coom brays is the accepted form, which is what we basically have had in our narratives since about 1993 or so.
However, sometimes I noticed the narrator would slightly change pronunciations of Cumbres in the same program. Hey, if we had the big budgets we could hire some Hispanic babe like Daisy Fuentes!
Then nobody would worry about the words cause they wouldn't be listening anyway! Guess thats why they are all on those TV hosting gigs.
Appreciate the help guys!
