I am researching on my Dad's family but have'nt had any luck. My Grandpa was Thomas Edward Irwin and Grandma was Cordelia(Katie) Irwin. They lived in the Kapron-Woodward area in Oklahoma. They had sons: Ralph Edward, Bill, Tom, George, Cecil, Howard, Clifford, & Milford. One daughter, Mary. Grandma(Katie)died in 1961 or 1962. Grandpa(Thomas) died before I was born(not sure of the year of his death). My father was Cecil. If someone can help with any information I would be grateful as I am at a dead end.
