I tried to post a reply and think it went to the wrong board!
I am the GGGGrandaughter of Robert Anderson Eagles &
Susannah...have been looking for her maiden name for
about 17 years!!!..You must have a family Bible or personal
records. I also have tales about RA, his military experience,
death, and a picture of Sarah Amelia, my ggg grandma.

I have a terrific lead to relatives of RA, just can't make the connection. The author of the geneo book THE SOURCE is Arlene Eakle (Utah). Many years ago she used to publish an EAGLE newsletter with some of her research. Most helpful was cemetary info she sent.....my uncle went to visit....
