I might have some ancestors related to you. My uncle did a family tree a couple years ago and my ancestors are from the same village Olcsva,Hungary but it would be the Toth line. You may be interested to that my Great 5x Grandfather married a Zsuzsanna Kosa on Jan 15 1793 in the reformed church in the village of Olcsava. Also, their fith child Janos Toth born on Jan 3 1803 married a woman named Zsuzanna Kosa. I might be able to get more info on the first Zsuzsanna, i know she was a orphan and her step father was Pal Szabo. This village has such a small population I thought there might be a chance that these people may be some of your ancestors. good luck with your search.
