Peter Yansen (Yanssen) was born abt. 1806 Somewhere in Germany. Anna Catherine Vogelsang was also born somewhere in Germany around 1810. They had a son by the name of Peter James Janssen B: September 1, 1832 in Helmstedt,Niedersachsen, Germany. I have been unable to confirm that date of Birth through Germany. Possibly because I used Janssen on the inquiry instead of Yansen. That is all I know at this point.
