Have you seen this?I used to live Portland, Or and I talked to some folks named Estabrook who lived in Vancouver, WA..... actually, I found their dog and I thought it was odd that we had the same last name (my maiden name is Estabrook) and we weren't related.Anyway, here is a posting that you may be interested in if you are still working on family tree.
It is still on the GenForum listing:
"I purchased this photo of this lady. On the back is the following information:
