Searching Heinrich Wilhelm Venghaus (he usually went by Wilhelm/William), born about 1818 in the Kingdom of Hannover; married 1846, Evangelical Church of the Holy Spirit, St. Louis, MO, to Johanna Catharina Louisa Rose, from the Kingdom of Prussia.

He was a pump manufacturer; 1850 census employed five other German blacksmiths; also a brass finisher; by 1860 had diversified into locksmithing. Is anyone familiar with a Hannover parish were a conjunction of this name,religion, and occupation might be likely?
