Thanks for a promt reply and the advice.
My grandfather was born in Heves Hungary, thats certain. There are no records of his births in Czech Republic, only his death certificate.
I will certainly follow the links you have kindly sent.
The name of my great grandmothers family might have been von or De Eszter-Gally. I have researched as much as I could the aristocratic names but to no avail. Any ideas?
