I don't know if you have had any luck tracking this ancestor down.
I recently had some success--I thought I'd share it with you.
My great grandmother Katie, was born Katarzyna Kasperska in the town of Stratyn Ukraine (formerly the Austrian-Hungarian Empire).
I am pretty sure the name Kasperski is traditionally Ukranian?.
She came over with her father (whose name was reversed and transcribed incorrectly-part of the problem).
Maybe that helps you.
Family lore says Katie had a sister and brother, but I don't know what happened to them.
