Matti Henriks' son Kotilainen was born 4-1-1847, in Finland.
Oskar Matts' son, Kaarle (Kalle) Heikki (Henrik), and Rosa Alina(Kotilainen)Kauppinen/Wakkila (my grandmother) were children of Matti Henrik' son Kotilainen and his wife, Kaisa Mantyniemi: born 11-21-1846. They had a total of seven children. Alma Maria, Selma Sofia, Olga Paulina, and Hilda Emilia were the names of their other four children.
I have been unable to determine when and where Oskar Matts' son Kotilainen died, and where he is buried. I would appreciate assistance that would help me solve this family mystery.
