Why?
Gluhareff is probably the American way of spelling the East-European or Russian name "Gluharev".

Exactly, the -ev and -s means "his". This means for Peters: "Peter his (son)". This is how many names were made in the old times.
So Gluharev was Gluhar's "(nick name) son.
And what means Gluhar?: THE DEAF ONE!!
