How very interesting Elizabeth, I wish I could read German. I will have to Google Crainfield and find out how it relates to Bannerod and Neider Moos. Ron Alt did much of the Alt research, his book was published in 1989. The furthest he went back was to Johannes Christoph Alt (1783-1844) who married Anna Margareta Ruhl. He was known as Christoph, I suppose to differentiate him from his father, Johann Heinrich Alt who married Anna Marie Dahmer. It is possible that Johannes Alt the school teacher could have been father or grandfather of JH. Unfortunately the only original German records that the family have relate to Christoph (1828-1873):- Certificate of Domicile when he took up a position as manservant and is signed with Archducal authority by the Mayor of Bannerod in 1848. He also received Certificates etc which were awarded by the Archduchy of Baden for military service.
