Mike,

I don't know much about the Cronin's of Portville, NY. This
is what I know: James Cronin (b. 1864 in NYS) married
Mary J. McGavisk (b. 1866 in Sartwell, PA) in 1887 in
Sartwell, PA. They may have had children with the names
James F., Mary R., & Eleanor.
If you have any additional information please let me know.

Regards, Paul Oliver
