Story Originally the Riedheim ministerials were the Lords of Graisbach, who had their noble seat in Riedheim and from then on named themselves after this place. Bertold the Riedhaimer is mentioned in a document from 1312. In 1384, the brothers Erhard and Winhard Riedhaimer von Riedheim came together to jointly manage their inheritance in Riedheim. Konrad von Rietheim is mentioned in 1347. The family initially settled in Remshart (today a district of the municipality of Rettenbach) near Günzburg; the headquarters near Holzheim was sold to the Riederer von Paar family at the end of the 14th century.
