I am looking for my biological father or any of his other children. I really don't know anything about him other then his name. He at one time lived in Michigan and possibly Montana. I know that he has two possibly three children. One son and deff. 1 maybe two daughters. I also know that he had at least one granddaughter, if I was told correctly she unfortunately passed away very young due to drowning. Also everyone involved is significantly older then I since my mother had me at 42.
Any help or info would be greatly appreciated especially because I keep running into brick walls due to how little I know.
