Sometime in the 1960's, I came into possession of a stained glass window from the estate of Commodore Cornelius Vanderbilt's granddaughter. I was told at the time the glass may have been a part of an original building on the estate which pre-dated the Revolutionary War. The glass itself measures approximately 19" in length and 12.5" in width. It has been re-leaded in places and framed in a "lucite" mold to stablize the glass. It is inscribed with the names "Wasshington & Newce" in the bottom-most panel. I have also been advised the colored patterns shown may be a family crest or coat of arms.
I am interested in any information or suggestion on where to research the provenance of this window, so any help would be greatly appreciated.
