I have a related Amanda, b.1873 in Kauhajoki, Finland. Her maiden name was Karvari. I believe John Koski was her second husband. They had, at least, these kids: Ida Koski, b. abt. 1899 MI and Pearl, b. abt.1902 MI. They might be your Koskis, too, I hope. Would you mind contacting me, I am writing a family book including Amanda and her descendants.
