Looking for Csanki and Pancel ancestors in Budapest and surrounding area.

Istvan Csanki (1870-1947) was a civil employee with the railroads. His second wife was Borbara Berki, from Zala province (1891-1960) in the south, near the Austrian border.

Istvan's parents were Stefan Csanki (d. 1889) and Judith Pancel (d. 1914). He had two older sisters, Julia (b. abt 1865) and Erzebeth (Elizabeth) (b. abt. 1868). Both were married but I don't have their spouses names.
