Lebenhan belongs to the diocese of Würzburg and the church books of the catholic parish of Lebenhan are filmed and available for researches at the archive in Würzburg. I couldn`t find any records at Familysearch.
You can ask there for single entries like the birth entry for Adam König (if you know the birth date). The address is: firstname.lastname@example.org
Give all the datas you have to the inquiry!
If you need someone for a research you can get in contact with me directly under: email@example.com
Hope this helps,
