Gertrud was probably born during the period 1715-1724 for which baptismal records are no longer available. The most likely parents for Gertrud were Anton Jungclas and Margaretha of Wirfus. They were the parents of Nikolaus (born in 1703; married Anna Barbara Lawen in 1733), Anna Katharine (b. 1705; married Cornelius Corneli around 1733), and Anna Maria (born 1708). Gertrud may have been the sister of Elisabeth Jungclas who married Christian Schaden in 1741. Gertrud was the baptismal sponsor for Gertrud Schaden, daughter of Christian Schaden and Elisabeth Jungclas, who was born on July 26, 1753 in Wirfus, and for Gertrud Weber who was born on May 29, 1757 to Johann Anton Weber and Maria Gertrud Heucher in Greimersburg.

The most likely parents for Johann Michael were Wilhelm Weber and Maria Muennich of Illerich who had a son Johann Anton in 1714 in Wirfus Muehle, and sons Matthias Josef in 1730 and Anton in 1733 in Illerich. The pattern of baptismal sponsors strongly supports this idea.
In 1735 Johann Michael witnessed the baptism of Johann Michael Weber, son of J. Anton Weber and Apollonia of Wirfus. He also was a baptismal sponsor for Johann Michael Schaden, son of Johann Anton Schaden and Katharine Kremer of Illerich who was born in 1745.
One of Johann Michael and Gertrud’s children died on December 31, 1755.

Johann and his wife Gertrud Jungclas Weber did not have any children. Johann and his wife Maria Wilhelmi had eight children and lived in Illerich. One of their children died on December 30, 1781; the child’s name was listed as Peter. Johann was a baptismal sponsor in 1765 for Johann, son of Philipp Jochem and Maria Katharine Jungclas of Illerich.
