Henry Stephan b. 1802 Metz, Lorraine France

Looking for any info on my great great great grandfather Henry Stephan b. 1802 in Metz, Lorraine France. Have very little info on him. All we have is the first name of his wife which is Mary and one of their children..which is John William Stevens (name changed when they came to U.S.). John was my great great granfather. Trying to find anydetails of Henry's life including the names of his parents if possible. Henry is my roadblock for this side of the family. So any help/info is greatly appreciated.

Thanks in advance,
