Good day all,
Some (unsourced but largely corroborated) online genealogies claim Pieter Aarjensz Brouwer is the son of Aarjen Jansz Brouwer and Neeltje Pieters Keesman. (two examples are linked from the attached Wikitree profile)
The recorded facts of Pieters origins come from his death recorded at Frediksoord (Vledder), Drenthe. He is given as being born at Wieringerwaard on 25 December 1780. He married Maartje Kornelis Kooi(j) in 1808.
The baptismal records of Wieringerwaard do contain an entry for a 'Pieter Oomis', son of Aarjen Jansz Brouwer and Neeltje Pieters but this baptism is performed in 1770.
This set of parents, Aarjen/Arien Jansz Brouwer and Neeltje Pieters [at first: Omis], are found in other Wieringerwaard baptisms in the period of 1767 to 1774.
Overlapping time with this couple is another local family, Aarjen/Arien Jansz Vader and Neeltje Pieters who are recorded in baptisms from 1770 to 1778 with a 'Pieter Arients' baptised in 1772. Possibly the same man is later married to Ariaantje/Aajaantije Pieters (later: Bruijn) with children baptised 1780 to at least 1795 including another Pieter in 1782.
In 1783 another set of parents, Aarien Jans Meijer and Aagije Pieters (later: Bakker) have a child Pieter. This couple is recorded to at least 1795 with a second Pieter born in 1792 (presumably the first Pieter did not survive childhood)
Meanwhile, there seems to be another couple, Aarjen Jansz de Wolff and Neeltje Pieters who are wed in 1766 - A Pieter baptized in 1781 to parents Aarien Jans de Wolff and Neeltije Pieters is possibly the child of this couple. Their early marriage date and their apparent 15 year absence in the records could point to Aarjen Jansz de Wolff being the same person known by the occupational surname Brouwer but there is nothing concrete upon which to make this conclusion.
Starting In 1782 we also find records mentioning what appears to be yet another family with parents Aarien Janzen Braaven (which considering the handwriting could actually be Brouwer) and Neeltije Pieters Keesman. Alternatively, this may or may not be the same A. Braaven that is found in earlier records as the husband of Trijntje Tamis.
I feel that given a) Pieter's marriage in 1808 (at which time he is still listed as bachelor and not a widower) and b) Pieter's children born from 1809 to 1829 that it is unlikely that he is the child born in 1770 to Aarjen Jansz Brouwer and Neeltje Pieters. Further, I think the association of the surname Keesman to the wife of Aarjen Brouwer is erroneous.
Any additional sources that might clarify Pieter's parents will be appreciated
