I have a Nicolaus Lux in my tree born 28 Nov 1840 in St. Nikolaus. His father is Johann Lux born 09 Jun 1800 in St. Nikolaus (died 29 Dec 1880) and his mother is Elizabeth Gettmann born 1807 in Tentlingen and died in St. Nikolaus on 25 Mar 1857.
I have Nicolaus dying in St. Nikolaus on 26 Feb 1900. His father is Balthasar Lux born 1770 died 1814. Balthasar's sister is Catharina Lux who is my ggg grandmother. Catharina married a Johann Jochum in Ludweiller. They had a son named Johann Jochum born in 1801 in St. Nikolaus. Johann, his wife Catherine Dreistadt and 5 children emigrated to Louisiana in 1850. One of the children Carl Yokum is my great grandfather.
I have information about Nicolaus Lux's ancestors, if you don't have them. His grandfather is Lorenz Lux. His great grandfather is Johann Lux. The information is found in a book I have called "Die Einwohner von St. Nikolaus von 1696-1900" It is written in german and has lots of Lux's in there as well as Jochum's... I will be glad to share information.Which of your ancestors left to the United States?
