I am the grandson of Jacob Mueller of Wertingen,Germany.I live in the United States.He is the father of my mother,Dawn (Miller) Costakes.Jacob came to America as a child,and I have photos of him when he worked at the Pierpoint Glass Company in New Bedford,Massachusetts.He became a police officer in the New Bedford police department.He married Elizabeth "Betty" Wilson.I am interested in any info. He is also known as John Jacob Miller.Perhaps it is a different Jacob Miler. but his home town is indeed Wertingen,Germany.
