Hi Debi,
just in case you do not know them yet:
In „Personenschatzungsregister der Kirchspiele Neuenkirchen und Steinfeld
von 1661“ there are two Clostermans in Steinfeld, viz:
vidua Clostermansche (vidua = widow)
having two horned cattles
and
Clostermans son Johan
went to Holland
More I do not have or know about.
Regards
Monika
Thank you Monika for the new information, I have not heard of this and I appreciate all leads.
