Hello. I am preparing an article for a news letter and it is about Andrew K. Hay. From my research he was quite a man. I understand you may be related to him. In reply to your question regarding John Hay; he was Andrew's nephew. I believe that they ran the Winslow Glass Works together after 1852 or so.
I would love to learn more of Mr. Andrew K. Hay and would like to include a photo or other likeness of him in my article if I could find one? He was involved in much industry in 19th century New Jersey and America. Have you been to his grave site?
