Dear Joke and Richard,
the history book about farmers in Oldenburger Münsterland , called "Die Bauernhöfe im Amte Vechta", shows some Wolke Kötters and Farmers in Bakum-Carum, Vestrup-Haustette, Damme-Sierhausen, Damme-Hanenkamp.
The church register of Lohne included this record:
Wolke Herman Dirk, born 11.March 1721 in Vestrup, parents Wolfgang Wolke and Anna
married 18.Nov.1749 in Vestrup to Catharina Maria Nortlohn
died 14.July 1790 in Vestrup
I don't know, wy this record included in the church register of Lohne, may be the wife Nortlohn (Nordlohne) came from Lohne.
I think the name Casper Schiltmeijer should be Caspar Schillmöller.
Schillmöller was a farm in Visbek since 1545.
I hope it help.
Werner
