Good catch Lindy, I looked at that a few times before I realized that it was spelled differently. Probably a typo in the middle name field on the profile since the source is there with Elbern and the biography states it is Elbern.
When I looked at the Find a Grave for Alton, it has the obituary listed which has it spelled as Elbren in the biography and the name at the top as Elbern and he has a child named Elbern. The child's page has a gravestone with spelling as Elbern, so the family name may be Elbern.
The marriage source on the profile has Alton Elbern, so the obituary on the Find a Grave may have had his name spelled wrong.
