Have you come to the 1700 in following your lines backwards? Have you reached the beginning of recordings? You need to read the church records yourself to establish the correct spelling of the names in the 1700s and hopefully find a hint on the origins of your ancestors.

Follow back any mentioning of your names, even if it's not your line.

The Chrisbacher book contains references to scholarly articles, mostly in Hungarian, about the resettling of the Bakony forest. You might want to engage a Hungarian researcher to look at these articles and see whether your ancestral names are mentioned there.
