I was able to get the baptism register (from Zentralarchiv der Evangelischen Kirche in Hessen und Nassau) of my ancestor Johannes Schönatin (alternative surnames: Schenardi, Schenardie, Schenardin, Schönardie, Schönarding, Schönhardti, Schönhartien, Schönhardt) from Alsheim, 1798, son of Mathias Schönatin and Catharina. I think they couldn't find anything else from his family, but I'll contact them again if need be.
I tried making contact with the Standesamt from Eich to see if they had his birth register but they don't. The same thing was said by the Landesarchiv Koblenz.
Could anyone try looking for information about him, his parents, or possible siblings? I thank you in advance for the attention.
