Seeking ancestry and descendants of Vaniczky and Korsch family:

My german speaking great grandmother: Maria Vaniczky B: 11 Sept 1884 in Kniesen, Szepes, Hungary. She immigrated to U.S.A. sometime between mid-late 1890s-1905.

Parents: Adalbertus Vaniczky and Sophia Korsch
in Gnezda # 192. Godparents Joannes Korsch and Julianna Matuscak.

I found her baptism record in FHL "Slovakia, Church and Synagogue Books, 1592-1910." Index and images. FamilySearch GS Film number: 1739196 Image number 687" but have been unable to find any other mention of those surnames - it is like they vanished.

I'm trying to determine if Maria had siblings, anything about her parents and their ancestry. I recently.saw the Vaniczky surname listed in Rudno as of 2005 but I have not discovered yet how to contact anyone there.

Any suggestions, resource referrals would be GREATLY appreciated!

Thank you!
Kathy
