It's been several years, but I finally came back to this site and did the free trial to dig up more information on my family.
I'm not sure that my family relates to most of yours since you all seem to have more related information, but I figured it'd be worth a shot at posting in the event that somebody finds a connection somewhere.
My name is Mark Vlcek, I'm currently 22 years old. My father is Ron Vlcek, he was born in Cleveland, Ohio in 1957. His father is John Vlcek, born around 1926. John's father (my great-grandfather) was Stephen F Vlcek, born around 1893 in Czechoslovakia and married to Anna Falatek (born ~1902). They apparently both immigrated here, then got married and moved to Cleveland, Ohio.
If anyone else has any information, I'd really appreciate firstname.lastname@example.org
