zoeheland on Family Tree Circles

Am looking for info on Katie Bell Hamilton (may have been born in Walker, Iowa) & Harry Irwin (may have been born in Paris, Iowa). Lived in the Lynch, NE Boyd county area. Had 4 daughters and 1 son:
Mary Grace was born on 23 May 1896.
Zoe Heland was born on 14 Aug 1898. She died in Apr 1972.
Ruby Jessie was born on 22 Jul 1902.
Harold Charlie was born on 13 Jan 1906. He died on 17 Aug 1965.
Velma Marie was born on 2 Jan 1909.
I have no information on their parents, siblings, etc. Any help would be greatly appreciated.
My dad was DUDE DARNELL from Lynch, Nebraska. Zoe was his mother.
