Hi Mary, My name is Kevin and I am not at all related to the Vunk's. However, I knew Hubbard Vunk, his wife Geraldine (with whom I worked many years) and his two kids Karen and Michael.
Hubbard was a jeweler and would design lovely pieces for Gerry his wife. Hubbard loved to bake and both he and Gerry were extraordinary when it came to this.
Karen, his oldest child, lives in NJ (I don't recall where) but is married and last I heard, they do not have any children.
Michael, moved to Boston MA where he attended Boston College and graduated with a business degree. Last I heard, he is still in Boston MA.
Unfortunately, Hubbard passed away a number of years ago due to medical neglect on behalf of a minimum of 5 doctors and a very ignorant staff at an MRI facility. Hub (as Gerry called him) had a pacemaker; and at the request of 5 doctors, he was instructed to get an MRI (which is strictly forbidden for anyone with a pacemaker). Well, as a result Hub suffered a massive heartattack and died while undergoing the MRI. There was a very big investigation by the Suffolk County DA and criminal charges filed against the MRI facitily. You should be able to find a lot of info there.
I spoke with his wife Gerry several years ago regarding this and we had been in touch but I have since lost her number. I believe Gerry is still in the Patchogue NY area. If you get in touch with her please ask her to contact me at firstname.lastname@example.org
I hope my information helps you with your research.
