I have just recently started researching my husband's family and think he is related to the Floyd Hadlock you are looking for information on. This Man was married to Clara and they had either 6 or 7 kids. My husband was born in 1951 and all I know about his grandfather is that he committed suicide before my husband was born. If this sounds like the person you are looking for , I have the sisters and brothers names. Maybe we can swap info.
