Hi Emil, If you're looking for his grandparents info a "Judy" Jeanette Louise Ingram b. 5 april 1936, McFarland, Kern Co., CA Died: Delano, Kern Co., CA Source: Suzanne Family Tree, trees.ancestry.com/tree/14808063/person/883362553.
Iris Irene Holland Prather B. 12 Dec 1915 Knox City, Knox Co., Texas Died: 15 Jan 1965, Delano, Kern Co., CA Source: same as above.
I didn't find anything on the two grandfathers. However, the Mortuary should have that information. Do a Google search for Delano California Mortuary. Successful Searching!
