I'm looking for info on John Chrzanowski b-8/20/1887 d-7/1971, Detroit, Wayne County, Michigan. It is believed that he immagrated to America abt 1907/1908 from Poland. He was married to Katherine (Kate) b-10/31/1887 d-6/4/1975, Alpena, Alpena County, Michigan. They had 7 children: Anna (Ann), Stella, Leonard, Helen, Stanley (Edward), Margaret and Theodora. He is listed in 1920 and 1930 Census Alpena, Michigan. He is listed in the SSDI Death Index for Michigan. I haven't been able to find any other Census Records on him. I haven't been able to find an obit on him either. His wife is buried in Alpena, Michigan but he isn't. He is also listed as living in Macomb County, Michigan at the time of his death, but I can't find anything on him there either.
I'm also looking for info on his parents and possible siblings.
Any help will be very much appreciated!
Thankyou ahead of time for any help that anyone can give me!
