Anna Margarethe Mertzenich was my paternal 6th Great Grandmother. She was baptized 11 March 1671 in the Sankt Blasius catholic church in Düsseldorf-Hamm. Her parents were Hermann Mertzenich and Elisabeth von Collen. The baptismal entry you can find here and below.

The baptism book was only recently made available online, for me that was very exciting to see the original entry from 1671. You can read about the church on Wikepedia.
Anna Margarethe married my 6th Great Grandfather, Cornelius Kauertz, 12 November 1702 in the Sankt Dreifaltigkeit Catholic Church in Düsseldorf-Derendorf.

The wedding church book also was also recently published online. An old postcard of the church is below.

Ann Margarethe and Cornelius had the following children, all baptized in the same church as above.
- 1. Henricus Wilhelmus Kauertz baptized 19 March 1704, godparents were Henricus Mertzenich, probably a brother of Margarethe, Wilhelmus Eickel and Elisabeth Nullmanns.

- 2. Joannes Jacobus Kauertz, my 5th Great Grandfather, baptized 23 September 1705, married to my 5th Great Grandmother, Maria Magdalena Elsen, died 29 August 1781 in Derendorf. They had eight children together. Below is his baptism. Godparents are Joannes Wilhelmus Mertzenich, Jacobus? and Elisabetha?

- 3. Anna Catharina Kauertz baptized 30 November 1706. The writing is hard to read.

- 4. Elisabeth Gertrud Kauertz baptized 20 February 1708. Married to Antonius Cremer. The couple had 3 children. Her baptism is below.

- 5. Maria Gertrudis Kauertz baptized 19 December 1709.

- 6. Winandus Leornardus Kauertz baptized 25 October 1711, married to Anna Helen Maria Magdalena Gast. They had 4 children. He was also married to Anna Margareth Butzong. They had 1 child. Winandus died 17 May 1745. His baptism is below.

- 7. Maria Catharina Kauertz, the last child, baptized 3 December 1713.

I was able to find copies of all of the children’s baptisms. I do not know when Anna Margarethe died. She was born in Hamm and died probably in Derendorf. A map shows the distance between the two locations. It’s only about 6.4 km or 3.9 miles.
