Thanks for your email, I'm sorry it took me so long to reply, I haven't checked my mail in a while.
Well, I am not thinking that I have enough info on your Marie Vojta - are you sure she was from Kralka? All of my relatives are from a town called Strakonice - perhaps if you sent the other info you had I could narrow down my info. I do have a few Marie Vojta's but none from that city. Who knows, Vojta is a rather rare name, perhaps we are related in some way!
My father and I have been doing family tree research for about 2 years now and even went to the CR this summer to visit - it was great.
Get back to me with that other info when you get a chance and I'll be glad to help (either way!)
Thanks again for the response - this was very exciting!
