I am looking for any information on Ira Dean Bixler. He would have been my biological grandfather but left when my mother was three. As far as I know he was born Aug. 21, 1940 and died October 26, 2005 from bone cancer. I know he has a daughter named Mary who was living in Chicago and his mother (my great grandmother) died 1998 if I remember correctly from Alzheimers and was also Mary. As far as I know most of the family was from Illinois. Any help is appreciated as there are some family medical conditions that have gone unanswered. We are aware my mother had an older half brother and Mary was her half sister. Ira, better known as Dean, married several times so this might be a little tricky. At one point he married my grandmother Kay Knauss from Ohio.
