I can serve with the following information about FILLINGER's in Hungary.
Fillinger's crest (GyõR) is characterised by a FISH.
Two family with the same Surname Fillinger one in Pécs other in Gyõr, Hungary unified Ferenc Fillinger (later Falkay), Gyõr and Emma Fillinger, Pécs their son: József Falkay /1919/ and daughter: Magdolna Falkay /1923/.
Our family has a photo with the following Fillinger family members on it:

I am personally closely related to József Falkay, grandfather and Ferenc Falkay greatgrandfather and Ferenc Fillinger great-great grandfather.
Should these names help somebody to find real connection, I am more than pleased.
I am also aware of the fact that one of my grandfather's (József Falkay) cousin was Antal Fillinger, who has 2 sons: 1.Antal Fillinger, living in Germany 2.Sandor Fillinger, in South Africa
