Isac Patriarch, Bickert is mentioned 4 times in 1604. He died around 1604. His designation in the Stühlingen family tree is 'B1'.
Isac Birckhert never appeared on the protection list. We know about him only through estate proceedings e.g. [R1443; 09.28.1604]. This record also establishes a link between Raphael and Isac. It is likely that this is the Isak mentioned in the `Urfehde Affair` RR#10:. .
