I don't have too much information but I will be happy to share what I do have. In 2007 I did quite a bit of digging after information concerning my grandmother. Her maiden name was Bukovi Mária, born in Domoszlo Sept 1880.
I was able to track her parents, grandparents and the name of her great grandparent.
Her father's name was Bukovi Antal and traced backward from him.
The reason why I also included Felsö-Nána is that Mária's mother's maiden name was Kozma Mária who was born in Felsö-Nána. My grandmother was married in further west in Szabolcs in a town called Ajak.
