Longevity ~ Leendert Monster (1827-1918) in Pella

Leendert Monster was born on 24 June 1827 in Strijen, Holland, as a younger son of Jacob Monster (1785-1873) and his second wife Neeltje Noorlander (1789-1859). She is a daughter of Eldert Noorlander (1753-1794) and his wife Leentje Jabaaij (1761-1822). Leendert's paternal grandfather, Pieter Monster, originated in Sint-Anthoniepolder, Holland, and moved to Strijen, where he died on 29 December 1819, aged 77½.

At the age of 22, Leendert Monster married 26-year-old Lena Kamp on 27 March 1850 in Westmaas. Lena was born on 7 February 1824 in Westmaas. Her parents are Willem Willems Kampen and Grietje Brusse. Lena had first married Cornelis van der Hoek on 26 April 1847 in Westmaas. They had a daughter Grietje and a postumous son Cornelis jr. who both died at the age of 1. Cornelis sr. was born on 15 November 1824 and died on 18 May 1849, both in Westmaas. Ten months after his death, Lena had a new husband.
On 11 August 1850, 4½ months after her second marriage, Lena Kamp gave birth to another daughter named Grietje. A son Jacob died after 6 months in 1852. A second son named Jacob, born on 24 February 1853 in Westmaas, survived infancy.
Shortly after the birth of their son Willem on 14 May 1854 in Westmaas, the family left for the USA where they arrived later that year. The next year Leendert's elder brother Eldert Monster, a widower, arrived in the USA with his sons Jacob (10) and Anthonie (7).

Nollius Hajonides van der Meulen (1862-1907) drowned

The “SS Berlin” was a steel ship of 1775 tons, build for use on the ferry service from Harwich to Hook of Holland. On Thursday 21 February 1907, around 5 o’clock, a huge wave struck the ship, causing her to become impaled on the tip of the granite breakwater at the entrance to the New Waterway, west of Rotterdam. A Dutch lifeboat attempted to offer aid, but the rough seas rendered it impossible to approach the stricken vessel. Around 6 o’clock the ship broke in two, drowning the majority of the passengers. Later, 16 survivors were rescued, while 128 people had drowned.

Nederlandsche Staatscourant, 5-3-1907

One notable passenger who drowned was a King’s messenger, Mr. Herbert, travelling with diplomatic bags. Another victim was Hendrik Spijker of the Spyker car company. The main subject of this blog post, Nollius Hajonides van der Meulen, was also killed in this disaster.

Christina Kotting married her first cousin Adrianus Nieuwenkamp

Adriana Kits

In a previous blog post, I wrote about Jan Kits Nieuwenkamp (1811-1870) after I stumbled upon a newspaper article. He had been travelling with a steamship when it hit a rock, and he drowned. Recently, I came across a picture of his sister Christina Nieuwenkamp (1809-1887, below right). Christina married Jan Ludolph Kotting (1809-1844) who was clergyman, successively in Kwadijk and Alkmaar in Holland. Jan and Christina are both children of Jan Mattheus Nieuwenkamp (1764-1824) and his third wife Adriana Kits (1774-1881, to the right).

Jan Mattheus Nieuwenkamp and his wife Adriana also had a son Abraham, who was baptised on 4 March 1800 in Amsterdam. Abraham Nieuwenkamp (23) was a bookseller when he married Petronella Kotting (31) in Amsterdam on 23 May 1823. Petronella is a daughter of shopkeeper Jan Ludolph Kotting (†1830) sr. and his wife Jannetje Brinkel (†1797). Within a year after her wedding, Petronella died on 18 May 1824, 8 days after giving birth to a dead daughter.
Her widower, Abraham Nieuwenkamp, married his first wife’s younger sister Geertruid Kotting (28) on 24 February 1826 in Amsterdam. Geertruid was baptised on 21 June 1797 in the Zuiderkerk, another church in Amsterdam. They had issue, including a son Adrianus Nieuwenkamp, born on 30 November 1835 in Amsterdam. Geertruid Kotting, aged 50, died in Amsterdam on 15 August 1847. Her widower Abraham Nieuwenkamp died in Amsterdam on 1 January 1866.

Christina Nieuwenkamp
in widow's clothing

Christina Nieuwenkamp (to the right) was born on 5 May 1809 in Hasselt.  Her husband, clergyman Jan Ludolph Kotting, was baptised in Amsterdam on 12 February 1809 with witnesses Anna Maria Kotting and his grandfather Jan Ludolph Kotting sr. The parents are pharmacist Gerardus Kotting (1785-1852) and his wife Maria Elisabeth Gude (†1849). 
Jan Ludolph died of scarlet fever at the age of 35 on 29 May 1844 in his parent’s home in Alkmaar. After a widowhood of 43 years, Christina Nieuwenkamp died on 23 July 1887 at the age of 78. They had 7 children, including a son Gerardus Kotting, who was working as a pharmacist, and a daughter Christina Kotting.

Christina Kotting was born on 17 December 1841 in Alkmaar. She married her first cousin Adrianus Nieuwenkamp in Amsterdam on 7 May 1868. Adrianus is the son of Abraham Nieuwenkamp and his second wife Geertruid Kotting (as described above). At the age of 82, Adrianus Nieuwenkamp died on 20 July 1918 in Haarlem, Holland, and was buried there on the 23th. His widow, Christina Kotting, died in Haarlem on 10 February 1921.

Common Latin Terms for Family Members

When doing genealogical research, you may stumble upon some words of Latin. For centuries, the church provided for marriages, baptisms and burials, and Latin has been the standard for the Roman Catholic liturgy since the 6th century.

If a Latin term ends in “us”, then it refers to a male; if it ends in an “a”, it generally refers to a female. For example, “avus” refers to grandfather, “avia” to grandmother, and “avi” is used to indicate plural grandparents. “Proavus” means great grandfather and “proava” means great grandmother. So, “meus avus est pater mātris meae” can be translated as “my grandfather is my mother's father”.
The Latin language has different words for aunts, uncles and cousins, depending on whether they are on the father’s side or the mother’s side. An aunt, father’s sister, is “amita”, while an aunt on mother's side is “mātertera”. A cousin - a mother's sister's child - is “cōnsōbrīna” when female, and “cōnsōbrīnus” when male. The word for a cousin on father's side - when he's a child of father's brother - is “patruēlis”. Thus, in the table below I have focussed on general words for family members.

It's my 12th Blogiversary!

On  17 January 2013   I published my 1st post for this blog,  so  today is my  12th   blogiversary !

My genealogy research file contains ancestors from January 2003 onwards. Those are ancestors of my father's mother, so I must have started my research even earlier. My paternal ancestors, the Bos family in Cillaarshoek were the ancestors I started with.
My ancestors with the most children are Otto van Driel (1756-1832) and my male-line ancestor Cornelis Bos (1813-1888): both had 17 children with 2 wives. In the 17th century Arij Peijnsz. Hogerwaert and his wife Trijntje Willems had 16 children together.
The couple Gerrit Korver and Neeltje Bloet (±1640-1727) were married for over 66 years. When my ancestor Jan Pieterse Vasen died on 11-8-1702 in Ottoland, Holland, he was "around 100 years old and had been blind for 3 or 4 years".

My favourite blog posts of my own ancestors are:

1. Arie de Sterke (1796-1892) fought in Russia and at Waterloo
2. Thomas Brullee's Whaling Expeditions of 1687 and 1712
3. Bos is a common name in The Netherlands

Ancestor Score Completeness Statistics - 2025

Geneanet defines the Ancestor Score as 

“comparing the number of possible ancestors with 

the number of identified ancestors on a 10-generation report”. 

Inspired by the Ancestor Score - or “Completeness Statistics” - of other blogs, and GeneaNet's definition above, I generated my first one in February 2016. Since then I haven't just been able to linearly increase my known ancestors. Instead, I had to remove a whole line of wrong ancestors in 2018. Since then I've managed to add new ancestors - mostly thanks to publications by others about people who were living before 1700. Published transcriptions also helped to find additional ancestors.

Currently, I have identified 5700 different ancestors.

     *) The years 2016, 2019 and 2020 feature an ancestor score of February, 2018 has an August score, 2021 and 2022 have a January score.

   **) The Bandwidth of a generation is determined by the earliest and latest known birth or baptism date within that generation.

   ***) I have many ancestors in places like Sint Anthoniepolder, 's-Gravendeel, Wieldrecht and Hendrik-Ido-Ambacht, where pre-1800 baptism records are (mostly) missing.
