Back in December, I received the following email.

Hi,

I think this might be a good candidate for the baptism of Trijntje Sijbolts

Doop 11-06-1744   Groningen; Nieuwe Kerk
 
Kind Trijntien
Geslacht v
Geboorteplaats Groningen; Nieuwe Kijk in 't Jatstraat
 
Vader Sibolt Berents
Moeder Lammigje Hindriks
 
Bron Algemeen doopboek Groningen 1733-1754
Collectie DTB (toegang 124)
Inventarisnummer 150

If this is the right one, Trijntje would have been 18 when she married Hendrik Jans and assuming he died soon, she may have had a lover who consoled her a bit too much after her husband died and with the shame of having an illegitimate child she couldn't marry easily again till the child had a certain age and would be able to take care of himself. (although 11 looks a bit young I would not be surprised) or maybe she left him under the care of someone else.

Greetings from Korea.

I too had stumbled upon this same record but have failed to publish it on this site due to no absolute proof of validity.  It does make sense that mother Trijntje was from Groningen and probably was born there.  She returned there after the death of her first husband.  What other reason would she have to migrate to Groningen?  Below is the record found in the baptismal registries.

Yes, Tryntien (Tryntje) would have been 18 at the time of her first marriage - should the above record prove to be valid.  She married Hindrik Jans in 1762 at both Uithuizen (where she was living at the time) and Eppenhuizen (the city where Hindrik Jans was from).  Being married in both locations shows that Tryntje's family was living AT UITHUIZEN in 1762.  She appeased both families in this way: both would have had the opportunity to attend the wedding. 

How would we begin to prove this record?  We can look for a Sibolt Berents living in Uithuizen around 1762.  Or, should he have been passed, his wife Lammigje Hindriks.
