Louis Fiolkoski is the brother of my ancester, Joseph Foelle Cofsky. Joseph's descendants became Cofsky and Cofske... Louis' descendants became Kasky and Cofske, from what I've seen.
I have Louis married at least twice, and I have their son Louis as Kasky, but only lived a few months. It is the only son I could find in the church record with Adelaide. She died in 1852.
There is a marriage to Marie Anne Theriault in 1853. I have 3 children, and if there is a Louis I didn't have him... perhaps I missed it or have incorrect info.
If you would share info with me I'd appreciate it. Feel free to contact me directly!
