Whether the Lords of Winternheim came from Groß-Winternheim or Klein-Winternheim cannot be answered without further investigation. In 1235 they were named for the first time as the Lords of Winterau and thereby by the name that they bore in the time that followed. Father Hermann Bär has carefully uttered the assumption hitherto held up as certainty that the Lords’ estate before the middle of the 13th century passed by way of a daughter of the house temporarily to the Lords of Leien. In so doing he refers to a document by which the brothers Philipp, Friedrich and Heinrich of Leien ceded for themselves and their heirs all rights at the "Sandhof" to Eberbach Monastery, which for its part forwent all levies that it had imposed on them and their father.
