I would love to make a definite connection here.
These are not my directly lines, Capek and Dubsky.
However Kuncl or Kuncel is, but I only have two names from the late 1700 and early 1800.
Have you taken the Family Finder Family Tree DNA test? That would be a great start to see who you are matched with and perhaps if it is me, then we can research this further.
