I found this obituary. Could it be their family? Look in the surviving family members for names to research that fit your bmom's age/relation.
RootsWeb: HOLMES-L [HOLMES] Roger Boone Holmes obituary
I believe she would be Linda Lee Holmes. According to PeopleFinders she's age 57 and has a son age 26 named Rodger B holmes. Looks like she's also been associated with living in the same residence as Edward and Edna Holmes.
There are 3 Rodger Holmes' listed on Facebook. Look at the pictures and see if you can see any resemblance to yourself.
I didn't pay peoplefinders, so I don't have the phone number.
I also show that Bluette Holmes from Butte is 41 and alive and well. I also show a Bluette holmes who graduated from Butte High school in 1994.
