Krieger's Olm Germany to West Virginia

What a great forum.My great grandfather came to this country from Germany in the late 1800's.I've been told he came from the Krieger family in Olm, or from Prussia (my geography is poor at the moment).He settled in Wheeling, West Virginia, had at least one son Milton.Any information about Krieger's from Olm or Prussia would be appreciated.Thanks.
