Ancestor Score 2019 - a new begin

Inspired by the Ancestor Score of other blogs, I generated my own in February 2016. Shortly after posting it, I had to remove several wrong ancestors, decreasing my score. Later that year I was happy to find more new ancestors to compensate for the loss. 
In August 2018, however, I had to remove a whole load of wrong ancestors*** that were partly replaced by already existing ancestors due to inbreeding among my ancestors. Thus, my ancestor score had been decreased forever. Therefore, I decided to create a new 2018 ancestor score in August (replacing the one in February) to be able to continue this series of posts.

Now it's time for a new Ancestor Score post! 

Geneanet defines the Ancestor Score as 

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


My Ancestor Score at generation 10 in the period 1600-1722 is 79.5%. It will never reach the 100%, because some cousins intermarried in generation 7. 

The total number of my known ancestors - starting with my parents (generation 2) - is now 4520. 

The most common surnames among my ancestors are Van Driel, Oerlemans, Spruijt, Brand, Bos, Van der Giessen, De Jong, Van der Linden and Smits. The surnames De Jong, Bos and Smits are in the Top 25 of most common surnames in The Netherlands. The most common male given names among my parents are typically Dutch names like Jan, Cornelis, Pieter, Willem and Adriaan. The most common female given names are Adriana, Maria and Elisabeth.
My great-grandparents
Pieter Klootwijk & Adriana Brand 
The most common places of origin of my ancestors are Dordrecht, Sprang-Capelle, Sint Anthoniepolder, Ridderkerk, Strijen, Streefkerk, 's-Gravendeel and Dubbeldam.

Beatericx Wouters Roothals (±1595-1653) and Jan Dericxsen Antonissen van Nederveen are my only ancestors that had a triplet. My own mother was born as one of a twin. 
Jannigje Thomasse Brullee (±1684-1747), wife of Joost de Bondt, gave birth to 14 children. This couple was married for 43 years. Neeltjen Claes Bloet (±1640-1727) and Gerrit Maertensen Korver were married for 66 years. My great-grandparents Pieter Klootwijk (1875-1964) and Adriana Brand (1880-1965) were married for 61 years.

  ***) I have many ancestors in places like Sint Anthoniepolder, 's-Gravendeel, Wieldrecht and Hendrik-Ido-Ambacht, where pre-1800 baptism records are missing. 
  **) The Bandwidth of a generation is determined by the earliest and latest known birth or baptism date within that generation. 
  *) All years feature an ancestor score of February, except for the August score of 2018.
