I believe my ancestors arrived in Aldebro in the 1760s as part of Count Grassalovich's resettlement of the area. Their surname was variously spelled Schweitzer, Schvaitzer, Sveitzer, Svajcer, Schaitzer (among others). They were Catholic.
I have written Aldebro town council, the Heves Provincial museum, and various web sites but have not received replies.
I understand the Count's holding were extensive. I would like to know with a degree of certainty the area my ancestors emigrated from and records from that time I might pursue.
I have been unable to locate a copy of the following book. Does anyone know if it provides an answer to my query?

Thank you in advance for any help you might be able to provide.
