You're "on the ball"! Found Idelle's news obit in which she was survived by Mrs. Robert J. Baker (sister of Austin, TX) and two nieces. Your mom born 1927 and her father died 7 Sep 1933? You and I are probably "baby boomers"? Your grandfather's brother, Roy Francis Jennings (19 Jul 1900 - 12 Aug 1964), died childless? Are there many survivors in your family?
