How do I find information about court with some insurance company and Jason P. Mountebank in 1960/1961 please?

Good morning -

Several sites have this story as being an urban legend. Snopes is the most detailed of all of the sites. In my searches I could not come up with anything about Mountebank other than hoax/urban legend sites. The site you gave has a disclaimer both at the bottom of the page ("All information on this site is, to the best of our knowledge, false."), and in their FAQ that everything on the site is false. (Frequently Asked Questions)

However, it might me worth emailing the webmasters of the All-Lies page to see from where they got their information. They might have something that they didn't put on the site that makes the story true.

Hello,

I did a very quick ProQuest search looking in NY Newspapers for 1960-1969 and found nothing for a Jason Mountebank.

I'm not familiar enough with legal research to suggest how to look for a civil case in New York, but I'm sure someone else can if such a person existed.
