I found two marriage records for Frank ADAMSKI in Alpena, MI
First a marriage to Frankie MAJEWSKA on 7-Oct-1895.He lists his parents as Stanley ADAMSKI and Mary SOBELESKI.Bride's mother was Catherine GEGLEWCZ.
Second a marriage to Josephine BRYSSA on 12-Jan-1910.Again he lists his parents as Stanley ADAMSKI and Mary SOBOLEWSKI.Bride's parents were John MICHALSKI and Margaret KOWALSKI.

I can only see a transcription for the above, not the actual image.It seems odd that two people older than himself are listed as foster children.
I'm inclined to believe that Frank's father's name was Stanley simply because Frank was alive to give that information on both marriage records.We don't know if the person who gave the information for his death record really knew what his father's name was.
