Nicolas TRIERWEILER was born on 6 April 1764 in Olk, a small German village located about 5.5 km (3.4 miles) from Rosport in the Grand Duchy of Luxembourg. Nicolas was the son of Johann Gerard “Gerardus” TRIERWEILER and Elisabetha KERSCH. He had a brother and three sisters as well as five half-siblings from his father’s first marriage to Maria Magdalena “Madeleine” GANZ. It is not known at this time when his parents died.
Nicolas was a farmer (Ackerer) in Olk. The area had good arable fields and numerous streams; the wide valleys were well suited for grazing. The name of the village probably originated from the Roman-Celtic word Olca, a term for fertile farmland.
Nicolas married Catharina HOFFMANN, daughter of Carl HOFFMANN and Angela ROSPORT, on 8 March 1791 in Welschbillig, to which Olk belonged.
Catharina was born and baptized on 18 January 1764 in Girst, Grand Duchy of Luxembourg. Her godparents were Wilhelmus HECKER and Catharina MILBACH of Girst. When I found this baptismal record I was reminded that the information found in the family book compilations are wonderful for finding the families but events and dates have to be checked. The entry in the Family Book for Welschbillig, which includes families for Olk, incorrectly listed her date of birth as 1 August 1764.Catharina’s father died when she was about 16. A death record has not been found. His death has been estimated at before 1780 as this was the year of his widow’s next marriage. Catharina’s mother, Angela ROSPORT married Theodor ADAMS on 26 January 1780 in Rosport. Two years later, Catharina, at the age of 18, became a godmother for her sister Anna Maria’s son Theodor NICOLAI on 20 September 1782 in Girst. Her step-father Theodor ADAMS was the godfather of the child. The record is written in a beautiful handwriting.Nicolas was 26 and Catharina was 27 when they married. Two and a half months after their marriage Catharina gave birth to their first child. On 30 January 1793, three days after the birth of her second child, Catharina’s mother Angela died.Nicolas and Catharina had the following children:
- Matthias was born on 23 May 1791 in Olk. He married Anna (Angela) LUDOVICI before 1815. They had 10 children from 1815 to 1837. Matthias died on 4 May 1843 in Olk. His wife Anna died on 7 February 1856 in Olk.
- Peter “Petrus” was born on 27 January 1793 in Olk. He worked as a farmer (Landwirt). Peter married Susanna LUCAS, daughter of Bernardi LUCAS and Odiliae HAMM, on 1 March 1824 in Mesenich. He died on 19 November 1835 in Metzdorf. His widow remarried after his death.
- Anna was born on 22 July 1794 in Olk. She married Mathias SCHWARTZ, son of Lorentz “Laurentius” SCHWARTZ (1791-1860) and Magdalena HALER, on 17 January 1820 in Osweiler. She died on 21 March 1853 in Osweiler. Anna and Mathias were my children’s ancestors.
- Susanna was born on 19 April 1796 in Olk. She married Matthias KIRSTEN (1801-1846) on 19 October 1825 in the parish of Welschbillig. She died on 3 October 1845 in Ruwer.
- Klemens-Christoph was born on 1 November 1797 in Olk. Nothing further is known.
- Maria Eva was born on 14 September 1800 in Olk. She married Heinrich MERTES (1792-1859) on 10 February 1836 in Ruwer. Heinrich was a widower with four children. Maria Eva died on 1 October 1845 in Ruwer.
- Peter was born on 9 April 1805 in Olk. Nothing further is known.
Nicolas died five years after the birth of their last child on 2 November 1810 in Olk at the age of 46 years. His widow Catharina died on 24 February 1815 in Olk at the age of 53 years. Nicolas and Catharina’s dates of death were documented in their daughter Anna’s marriage record.Most of the information on this family was gleaned from the German Family Books. The Catholic church records for Welschbillig are held by the Bistumsarchiv Trier and have been microfilmed. They are not available for loan and access in Europe is limited to members of the Church of Jesus Christ of Latter-day Saints. Documenting this family will not be as easy as for families who lived in Luxembourg during the same time period.Sources:
