OJ Plesek:
I see from the number of posts that you are a new user. There are some conventions that you should follow when using these boards.
1. You posted the same message 3 times to this board. Ancestry now has an edit option for authors, so you can go back and delete the two extra messages. I had a duplicate LONG one and was embarrassed for about two years, until they allowed me to delete it.
2. It's ok that you posted to two Moravian boards, because you might not know which region of Moravia she was from. Generally, though, the regular readers will check all the boards for the Czech Republic.
3. It is absolutely essential that you give as much data as you already have. You should go read some of the other posts in the board to see what other have done. You will find that there are maybe a dozen or so participants who help, but only if they have a chance to solve your problem in under an hour. (My husband's colleague called me with a problem he had been working on for 15 years, and because he gave me one very important clue, I was able to find the answer in 40 minutes. Really.)
4. So what would we like to see? Birth date, even if approximate, location in US the subject immigrated to, immigration date, even approximate, town where from, even if it is a phonetic spelling as you remember someone hearing it. If you were to say "she's from Dolnee Lowcatch" a Czech reader would know you meant "Dolni Loučky".
So any details you have, however insignificant they seem, could help out. Otherwise, unless someone who has already added Anna to their tree happens upon your post, you won't get any responses.
We tend to divvy up the work. A few of us find more clues in the US, the participants in the CR look at the various archives online. Do go take a look at the last dozen or so postings on this board. It is very educational.
