searching Ringheim

It reacently came to my knowledge that my great grandfather, Ivar P Ringheim, had an unknown brother who emigrated to US in his early years. His name is unknown but his surname/farm name was Ringheim. He must have been born in the 1840´s or 50´s. Anyone have an ancester named Ringheim fitting this thin information please contact me on [email hidden]. Svein I Ringheim svein i ringheim
