Hi Della - a few years ago my family were privileged to visit Harry Northwood's granddaughter at her home in Wheeling (WV). We were accompanied by Harry's great nephew. http://i2.tinypic.com/qzfcsm.jpg
The photo shows Harry's great nephew and his wife on the left of the shot, then in the foreground is the late Miss Elizabeth Robb (Harry Northwood's granddaughter) and on the right are Steve (standing) and me (kneeling).
Miss Robb's home had many examples of the finest of Northwood's glass. It was an incredible and unforgettable experience. Possibly the most amazing thing for me was when I was allowed to hold in my hand a miniature cameo carving of the head of Shakespeare that Harry had done when he was a student. The cameo was taken out of its locked showcase and placed into my hand. I froze. It was one of the most memorable moments of my life.
