I'm researching the Chrzanowski Family of Alpena, Alpena County, Michigan. This is what I have:
John Chrzanowski b-8/20/1887 d-7/1971
married Katherine Anna Przeslawski b-10/31/1891, Alpena, Alpena, MI
d-6/7/1975, MI she was buried at Holy Cross Cemetery, Alpena, Alpena, MI on 6/9/1975. Her parents are Valentine Przeslawski and Frances Budnik. They had 7 children, Anna Wanda, Stella A, Leonard C, Helen F, Edward S, Margaret M and Theodora M. I can't find anything on John. When I looked up Katherine at the Cemetery, there's a person buried on the same plot as Katherine. The person is Meczyelas Chrzanowski b-6/14/1888 d-9/28/1932. Was buried on 10/1/1932. I don't know if this person is a man or a woman. I don't know how this person is related to Katherine. I haven't been to the Cemetery. I found it online.
I'm trying to find out who John's parents and siblings are and where he was born at. I'm wondering if Meczyelas is John's Polish name. I did ask someone about this and they said that the name would be spelled Mieczyslaw in Polish and is a man. Which on the Cemetery Records it could of been spelled wrong. When I search online on this name it comes up with John and Katherine's names and Census records.
Is there someone who can help me out of this brickwall?
