I am doing research on the Kotilainen family. My grandmother, Rosa Alina (Kotilainen) Kauppinen/Wakkila, was the younger sister Kaarle (Kalle) Heikki Kotilainen. Here is a summary of research results accomplished to date:
1.) Kaarle (Kalle) Heikki Kotilainen was born in Kivijarvi, Finland on 10/11/1872. I believe he came to the United States on 6/27/1896, and lived in, and raised his family in, Negaunee, Michigan. He was know in the family as "Henry".
2.) Emma Sohvia (his wife) was born 6/1/1877, I believe in Finland.
3.) Tyyne Meliita (daughter) was born 12/15/1896, in Negaunee, Michigan.
4.) Nelma (daughter) was born in Negaunee, Michigan.
5.) I do believe there were other children.
6.) Oscar Matts' son Kotilainen was the older brother of "Henry". He was born in Kivijarvi, Finland on 12/22/1870. I believe he may have lived in Negaunee, Michigan, Ashtabula, Ohio, and/or Pensylvania, Montana, British Columbia, and North Dakota, but we have not as yet obtained any other information on Oscar to confirm this. We remain unaware of his date of death, and his place of burial. We would appreciate any information that would help solve the "Oscar Mystery".
