I have more info for you on Curnell Fell.

Curnell Fell had five sons... Charles, Donald, Clarence, Ralph, Robert. 
Clarence had two sons: Howard (who currently lives in the Pittsburgh area with his wife and two children) and David Fell.
Robert had two sons: Robert Charles (my father-in-law) and Keith. 
Charles, Donald and Ralph had no children.
 
There are quite a few Curnell Fell great-grandchildren and great-great grandchildren, some living in PA and New York, some in Missouri and us in Oklahoma. 
 
My husband’s father, Robert Charles Fell has been researching the Fell family tree, which led us to Jacob Katzenstein Fell and this website.  He would have quite a bit more information on Curnell Fell’s family.  I can give you more contact info if you’d like.

Thanks for the previous info!
