Dear Cecilia, I am not sure if you are still on Ancestry, but I believe your father, Gyorgy Bubala was a cousin of my Grandfather, Anton Keller. His father, Antal Keller, had a sister named Borbala Keller who married Sandor Bubala and Gyorgy was their son who married Erzsebet Wahlkampf and had a daughter named Cecilia......Would love to connect and see if you have any information on my side of the family. Sincerely, Kathryn Harrington, USA
