[2] Fründ appears to have contracted a serious illness in 1447 which prevented him from completing the chronicle, so the text does not cover the peace negotiations and final treaty of 1450.
Fründ was married three times, to Elli Bumbel, then Adelheid von Tengen, and finally to Margaretha Giessmann.
He appears to have had acquired some wealth, as there are records of a dispute over his inheritance between his third wife and his daughter from his second marriage.
Similarly, Diebold Schilling the Elder used substantial portions of Fründ's text in his 1483 chronicle.
Fründ's chronicle was considered lost, and Heinrich Bullinger misattributed his text to one Ulrich Wagner.
