Looking for My Huff Relatives IN Nebraska

My paternal grandmother was Josephine Grace Huff, who maried Charles Newton Leonard sometime between 1900-1910. They had three children, Alfred Newton born 4/10/1910, Max Raymond born 5/04/1920 and Bonnie, birthdate unknown who died at about six months of age.

I know little about Josephine. She had several siblings. George?,Bess?, Rene (who drowned in the N.(?)Platte river at a youg age. There were more but I do not remember their names. There was a sister-in-law, Ohna or Ona. I believe she compiled a Huff family tree but I do not know if it was published.
