Katalin Sárkány, ákosházi - Sources

Hi Imre Maár, Maár Péter, Частный профиль, Частный профиль,

I'm looking for source to confirm Katalin's parents are Laszlo Sarkany and Katalin Aranyady.

In Ivan Nagy's books, Laszlo and Katalin are identify but they do have a daugther named Katalin but she seems to be married to soemone named Tobias Sibrik.

What are your sources ?

Sincerely,

Nicolas
