Searching for any descendants of Katharina Aicher and Mathias Unterrieder from Amlach, Spittal/Drau, Austria.
My grandfather Johann Aicher came mysteriously to the US abt 1900. We only know of his mother Katharina, stepfather Mathias Unterrieder and half brother Mathias Unterrieder II.
His grandmother was Anna Grillsberger. Johan settled in Wisconsin. I am searching for any relatives of Johan Aicher and Mathias Unterrieder.
