Alrighty, then! I was on the right track with "Sta". I also wondered about the last letter -- "b" or "k". Now, like Katka, I will go back and look at the whole page for those letters and compare to words I recognize, and learn how to read this handwriting a little more. And I can definitely eliminate the Marianna tochter and Jakub Musil otec combination I found in the baptismal records! I have 3 others to re-visit.
I assume, then, she was from Skřinářov.
