Looking for Ulbrich of Guttmannsdorf

Ulbrich family from Guttmannsdorf then transferred to Sohland, an der Spree.

My father's name was Manfred, his father was Hermann Ulbrich, wife Emma Bauer. Hermann Ulbrich was born March 31, 1906, died Nov 12, 1974 in Sohland. Any info related to this family would be welcome!
