It's my 13th Blogiversary!

On 17 January 2013   I published my 1st post for this blog,  so  today is my  13th  blogiversary !

In those years August 2018, October 2019 and January and November 2022 were the months with the most posts. Of course it’s not about quantity, but about quality. I've tried to achieve quality by writing about topics that arouse my interest. The stories on this blog are usually not about my own ancestors, but about people who catch my attention while doing research.

Nowadays, with my own ancestors, I often find myself stuck in missing or illegible sources. Therefore, new research often depends on newly available transcriptions of sources that have become available.
In villages with mostly missing sources, like 's-Gravendeel and Sint Anthoniepolder in South Holland, I try to include many people of those and their surrounding villages in my database, hoping that someone will marry a relative of mine, I didn't know before. Occasionally, I do find a small addition this way.
Other times I find small additions in genealogical magazines.

Surname Saturday - Bedé in Streefkerk

One of my 'brickwall ancestors' is Pieter Cornelisse Bedé who lived in Streefkerk, Holland. His patroniem is Cornelis, so that's his father's first name. The spelling of Pieter's surname varied quite a bit, such as Bedé, Bedee, Biddee and Bodee. It's likely his ancestors were foreigners, and the parson didn't know how to write their foreign surname. The surname could be a toponym if the family originated in Bédée, a village in Bretagne in France.

Pieter Bedé is a brother of Ariaentie Cornelisse Bedé. She married Bouwe Claesse van der Leck on 26 December 1659 in (Nieuw-)Lekkerland, Holland. They had children baptised with the names Claes, Cornelia (witnesses Dirk Cornelisse, Geertie Reijnders, Neeltie Claes), Jacob, Dirck (witnesses Jan Jansen, Jan Cornelisse, Annegie Herperts), Willem (witnesses Jan Cornelisse, Ariaentie Cornelis) and Jan.

Pieter Cornelisse Bedé married Ariaentje Cornelisse (de Groot) on 27 november 1667 in Streefkerk, Holland. They had children named Annigje (2x) and Cornelis. With his second wife, Sijchie Arijens (Aaldijk), Pieter had children named Cornelis (witnesses Pieter Arijenze, Bouwe Claeze, Cornelia Bouwenze), Ariaentje (2x) and Annigje.
Both Pieter's wives had a mother named Annechie, while Pieter's younger daughters Ariaentje may have been named after his first wife. Thus, the names of Pieter's children yield no convincing clues.

2026 Ancestor Score Completeness Statistics

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. I could partially replace them by already existing ancestors - due to inbreeding among my ancestors.
Therefore, I decided to generate a new in-between ancestor score in August 2018 to be able to continue this series of posts (and removed the wrong one of 2017). Since then I've been gradually able to increase my number ancestors.
The generation with the most known ancestors is the 13th generation with just 21% of the theoretically maximum number of ancestors in that generation. In the 12th generation I've found 41% of the theoretical maximum (if there wouldn't be inbreeding).

     *) The years 2016 and 2020 feature an ancestor score of February; 2018 has an August score; 2022 and 2024 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.
