Hello everybody,
what looks like Auclaw in a hand-written document is definitely the Eastern-German town of Anklam. This is a seafarers' town with a long tradition on the mouth of the river Peene into the Baltic Sea, formerly a Prussian town.
In British documents the "k" obviously was written as a "c" = Anclam, what is pronounced the same way. The "n" and "m" obviously are looking like "u" and "w".
I'm quite sure about this.
For further investigation, Andrea, and to find the roots of your great grandfather you could write to
Stadtverwaltung Anklam, Standesamt, Marktstraße 3, D-17389 Anklam, Tel. (from Britain) 0049-3971-202712. They can certainly tell you where the records of your forefathers are kept.
In addition I give you the following links:
