Baruch (Borach), Weyl is mentioned once in 1710. His designation in the Stühlingen family tree is 'W3.1'. His father was Meir (Mayer), Weyl - Donaueschingen.

Borach Weyl seems to have been among the 19 people who originally left Tiengen in 1683 [R1310; 05.11.1683] and moved through Stühlingen to Donaueschingen. He is mentioned only once [R7; 01.01.1710]. He had moved away under the darkness of night with his wife and children around April 23. 1709. The context suggests that he might have been a son of Meir (Mayer), Weyl, who happened to have died just around the same date. .
