Naphtali (Hertzl), Weyl is mentioned 2 times between 1720 and 1730. He died around 1730. His designation in the Stühlingen family tree is 'X1'.

Hertzl appears in the Donaueschingen account books of 1720 and 1730 as being under protection. There is insufficient information to associate him with a particular branch of the Weyl family, except that he probably came with the Jews evicted in 1683 from Tiengen [R1310; 05.11.1683]. .
