No, they were two different unrelated Herb Wetansons!
I thought it a bit odd that there could be two different Herb Wetansons of a similar age at the same time in the same area so I dug into it a bit more and found this:

Wetson’s was founded in 1959 by Harold Norbitz (1921-2001) of Dix Hills, LI and Carl Wetanson (1912-1995) of Woodmere. It was headquartered in Valley Stream.
Observing the McDonald’s formula for restaurant success, Wetson’s planned to duplicate it in New York — an open market at the time with no fast food restaurants.
Carl’s older son, Herbert, pushed for franchises all over Queens and Long Island before McDonald’s could enter the market. Herbert Wetanson was a successful race car driver well-known on Long Island.

It's nothing to do with this thread of course but interesting nevertheless!
