Family fragments - still searching

Austria, Vienna, Vöcklabruck

I'm looking for the church records of 

Eva R Sailer, * Dezember 22, 1856 in Austria, most probably
in Vienna.  (Sailer, Eva, 12/22/1856, Vienna, Austria)
Father: Georg Sailer, born in January 1830 in Blindheim, Bavaria.
Mother: (probably) Josepha, née Vesper, 'from Mähren'

Reputedly Eva had 7 siblings of which I don't have any
information. My hope is to find their names in the same  
parish like Eva...

My ggGrandfather George Sailer left Germany together with his
older daughter Eva.  The second daughter Theresia, who later became
my GreatGrandmother, stayed in Bavaria with her husband...


Any information on any of the above persons is greatly appreciated:
