Weinfurtner from Passau

[Dave Weinfurtner]

Hello:
My cousin (who lives in Germany and knows how to read the Old German script) looked at the Passau registers (online) and got our ancestry as far back as about 1700. she said the registers before that were destroyed in a fire.
Besides Weinfurtner, we are researching the names Wiederer (Wider), Schweikl, Weiss, Wieser, Mueller, Mayer, Muehlbauer, Loibl, Rankl, Vogl, Schink, and Goestl.
I would appreciate any help.
Sincerely,
Dave Weinfurtner
