My apologies for being so bad about responding sooner because I really appreciate your response and would love to compare notes with you.
My great-grandmother was Wilhemina Koskela, birthdate 10 Sep 1878. I'm out of town right now and don't have my database with me but when I get back home, I'll post all the names and dates that I have so far and see if we can make a connection. I'm fairly certain that we will because of Virginia, MN being in common. I'll also be curious to look through the photos to see if any of them have Johannes imprint.
Does my Wilhelmina's birthdate work with your info?
