BLStarkey on Family Tree Circles

I am searching for links to Claude Lorenzo Decker 29 Apr 1900-Mar 1980 or Nellie Decker Granger 19 Jan 1895- July 1973.
Claude was my husbands Maternal grandfather and our family history stops with him. I did however find in my in-laws papers a note for a Nellie Decker listing her death in 1973.
Their father was supposedly Lorenzo Decker but that's as far as I have on info for the family.
I have children for Nellie and Claude if anyone has family ties to them.
