I have visited the archive of the town of Münstereifel some years ago. There exists a list of people, who emigrated in the 19. century, mostly to N-America.
Under number 24 there is listed an Anton Lingscheid (shoemaker) from Schönau (near Münstereifel), who wanted to emigrate with his family [wife: Anna Elise Müller, 46 years old, children: Michael Anton 11 years old, Joseph 8 years old, Anton 6 years old] to North America on 17 March 1845. He got his permission on 19 April 1845.
Under number 3 there is listed a Johann Lingscheid (shoemaker) from Schönau, who emigrated in 1828..
