Rhoda Larinda Root

My great great grandmother name was Rhoda Larinda/Lorinda, b:1850 in Ohio, d: 1922 in Nebraska. Her father was Charles Root. No other info on him. She married George Frances Allen. I've searched the web as that is the only way for me do genealogy. I've come to the end of the line, any help or idea's would be greatly appreciated. The photo that is attached is her in the later years. the little girl standing beside her is granddaughter, Mable U Munsey who was my grandmother.

This my first time at this so I hope that I have done it right.
