I just replied to Coral's post and thought I'd reply to yours also.
My grandmother was Elyna Viola Jyrkas, daughter of Peter and Johanna Jyrkas (from Finland). My father, Lee Sprague, has spoken of your uncle Melvin.
I really have not been in touch with anyone from that side of the family and would love to hear back from you.
