My ancestor Henry Iloff emigrated from St Nicholas Saarland in 1840. This is in the Lorraine area on the border of France and Germany (now). The Egloff name is common in this area. Egloff is the French spelling of the name. If your ancestor said he or she was from France and Prussian and even Lorraine, this is the area. Check out Carol P. Christ Family Tree. There is a genealogy club in Morbach (now France) with huge amounts of info on all the families in the area.
