Inspired by the Ancestor Score - also called "Completeness Statistics" - of other blogs, and GeneaNet's definition, I generated my first one in February 2016. Since then I haven't just been able to increase my score, I also had to remove a whole line of wrong ancestors***. I could partially replace them by already existing ancestors - due to inbreeding among my ancestors, which didn't increase the score either. Therefore, I decided to generate a new in-between ancestor score in August 2018 to be able to continue this series of posts. Thus, in February 2019 I was able to continue with my Ancestor Score Series.
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 1600-1740 is 79.7%. 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 currently 4618.

*) All years feature an ancestor score of February, except for the August score of 2018 and a January score for this year.
**) 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 missing.
