The Mary Tichacek that you mentioned born in 1849 is my great-great grandmother. She married Anton J. Brunner and that is all part of my Mother's Father's side of the family. I have more info if your interested. It is on my webpage but I would rather not post the URL on here. You have filled in some holes for me on the Tichacek line and I would like to see more information if you have it!
