Hello Markus,
I see you have a Henriette Karoline Auguste ENGEL in your post to this list.
I have a Henriette Engel from Roebel who was a sponser at the christening of Heinrich Ludwig Holtz/Holz in 1814 of Sembzin. could this be the same person??
Do you have any Holz/Holtz in your records ? ? Heinrich's mother was Catherine Dorothea Holz.
