Jonas ben Salomon, Weyl is mentioned 42 times between 1712 and 1752. He died around 1743. His designation in the Stühlingen family tree is 'R1.1.2.1'. His father was Salomon ben Jacob, Weyl.
Jonas paid protection tax in 1712, and then from 1725 to 1742 continuously. It is possible, that he was living somewhere else in between, while his father continued paying protection tax in Stühlingen.. He was fined six times for minor infractions. It is debatable whether Jonas is the son of Salomon ben Jacob Weyl, or Salomon ben Nathan. But in view of the fact that Jonas received protection only 12 years after the latter, but 24 years after the former, that one appears more plausible. .
