My name is Orsolya Gantner and I live in Hungary. My grandfather was born in 1899 in Arad. Arad at that time was part of Hungary, but after the I. World War it was given to Romania. This was when my grandfather escaped to Hungary and two of his brohers and a sister went to the US.
I am not sure if this is related in any way to your husband's family, I just thought I would let you as this may help and inyour message yuo mentioned HUngary and Romania as well.
Kind regards: Orsi
