For those of you out there with Hungarian ancestry (or ancestors from the former Kingdom of Hungary), you will want to be aware of a great resource book by Jordan Auslander called Genealogical Gazetteer of the Kingdom of Hungary. This gazetteer is based on the 1877 Gazetteer of the Kingdom of Hungary. It includes incredibly valuable information for each town within the former kingdom.
Each town is listed with its present-day name, along with other names the town was known by. Most importantly, the book contains the number of persons in 1877 who affiliated with the primary religious denominations of the time, including Roman Catholic, Greek Catholic, Reformed, Lutheran, Jewish, etc. Then, within each denomination is listed the town where the closest place of worship was located. So, if your ancestors were Greek Catholic, and there was not a Greek Catholic parish in their town, Auslander’s gazetteer will tell you the appropriate place where records were kept!
This is an invaluable resource that I am constantly using as one of our Hungarian specialists here at ProGenealogists. There can be various challenges encountered when tracing Hungarian ancestry and this book can be a great tool in overcoming some of those obstacles.
