Thomas was my 2nd great-granduncle, Albert my 1st cousin, 3 times removed, and Mrs. Roy Pavy my 1st cousin, 3 times removed. Both men lived in Connecticut. I obtained the cross shortly after my grandfather's death. A room was set aside to display some personal items, and even though I was the last to pick what I wanted, I was delighted with this, and the other things I took 30 years ago. All items were related to genealogy or family history.

While looking at The Connecticut Historical Society Bulletin (Vol. 49 winter, 1984 #1), I came across an article called, The Charter Oak Artifacts on pages 126-157. There were many photos of items made out of the Charter Oak, including a crucifix just like the above, and many other items.
