In the website I sent you, there is information on several avenues you can pursue to get more information on your family and the towns they came from (including some microfilmed church records that are available through LDS Family History Centers).
In addition, there is is a "Vatieu" (probably the same family as "Vati"), who still lives in Sibiu, per the Romanian phone book:
l VATIU MARIA Address: Magura, Nr. 60, Sc. , Etaj , Apart. , SIBIU, 330, 2400, Phone: 069.438004
You could always try writing to her and see if she has more information about your family.
