My husband's great, great grandparents were Daniel "Dan" Eby and Nora Delphine Estabrook Eby that lived in Lincoln County, Oklahoma around the Sparks. OK area. I have photos of them from my husband's grandmother that are posted on my public family tree. Their son Clarence Eby is the father of my husband's grandmother Betty Eby Williams. John Leonard Estabrook was the brother of Nora Estabrook Eby. I hope this helps and if you'd like to see the photos (taken in Oklahoma about 1904 and again in the 1930's) just search for them in my family tree.
