Feiler update. I now know that the older children of Armin Feiler were born in Bielitz Osztrik-Szilezia, 2011 part of Bielsko-Biala a town on border of Western Galicia, Poland and Kenti aka Kety, Poland. The family then appears to have migrated to Pest where in Jan 1872 the mother Terez died and is buried in a cemetery at Salgótarjáni út. Any one with Feiler ties to either of these areas please contact me.
The father Armin/Herman migrated on to Temisvar where he is buried in the Jewish Cemetery in that town.
