Here's what I have for records from Germany:
Johann was born 28.10.1755 +and died 06.03.1830. He married oo 15.01.1782 Anna Elisabetha Lenz (Kempenich) and also married oo 05.09.1815 Anna Maria Porz (Weibern)
So 1755 Johann is the father of Bartholomaus.
The other children were born to Anna Maria Porz.
