help in locating previous owners

[bergy]

I'm trying to locate a couple of former owners of a car that I am restoring. No luck so far though in finding current contact information. If anyone knows of these folks, or can direct me in my search - please PM me.

B. Phillip Theriault – 1974 – August 1991
461 Allen Road
Porter Corners, NY 12859

C. Michal Grzyboski – August 1991 – April 2019
2 Tabor Road
Round Lake, NY 12151

Note - the time periods shown are for titled ownership, there were a couple of other owners who didn't title the car - I already have contact info for them.

Thanks, Bruce
