Thanks for your help!
I have been looking online at www. arcanum.hu/mol in the
census of 1715 and have found a number of towns where
there were Csonka. At first it was strange manoeuvering,
but using the arrows, and then the index button at the top
left of the data screen, you can see the counties, then the
jaras, and then the villages for each area. There are so many
places with Csonka I am trying to figure out where the 'first
ones' came from. Again, thanks for the web site and the
heads up about the research room.
