Saint George's and its parish priest held title to a fourth of all incoming tithes in Heidesheim. From the Middle Ages two documents are known in which Saint George's Chapel is mentioned. Both stem from documents that have come down from the Eberbach Monastery, and both deal with whether the "Sandhof" owed the priest the aforesaid tithe. While Provost Otto von Mariengreden could claim his entitlement between April and June from 1185 to 1196 as Heidesheim's priest, an arbitrary ruling from 23 December 1278 under reference to Pope Alexander III (who had died in 1181) lays down in writing that Eberbach owed Erkenbold – “Priest of Saint George’s Church in Heisensheim” – no tithes from the "Sandhof".
