Only one child is known for Peter Mahlberg. This is Joseph Mahlberg, born 1746 in Ellesheim, Germany. Joseph married Agnes Frings. They had at least three children, Anna Maria, Johann Gerhard, and Johann Peter. Descendants of Anna Maria Mahlberg Lethert and Johann Gerhard Lethert eventually emigrated to the US and many of the descendants have been located.
In Germany, the family also lived in the towns of Effelsberg, Lethert, Dollendorf. In the US, they lived in Wisconsin, Iowa and Minnesota in the earliest days, as did many emigrants from the Eifel area.
If you are related to one of these families, I would like to hear from you - to update my database and to share any further information on them.
