Hi,
Woedtke ( today Otok) was a small village in Pommerania/Prussia near Greifswald. It belongs today to Poland.
Lembach is located in Baden-Württemberg. Neither Woedtke nor Lembach has a standing bear in its coat of arm.
BTW, Berlin isn't the only german city who used a bear as "Wappentier", so the search must go on...
Immo
