Our most distant "known" male ancestor - Jacob Cornellis, who called himself KRUIZE, had an older sibling.  Her name was Trijntje.  She was born in 1763 at Eppenhuizen.

I wakened last night thinking to myself - Tryntje ("ij" and "y" are interchangeable) is a lead that might bring new information on how to penetrate or circumvent our genealogical brick wall - the illegitimacy of Jacob.  Perhaps.  It's certainly worth a try.  And what a wealth of information I uncovered.

I performed a search for Tryntje Hindricks that resulted in a multitude of possibilities.  The search would take me months to conduct so I needed to narrow down the leads.  Knowing that Tryntje's mother lived in the city of Groningen, I printed all the brides of the correct age who lived in Groningen OR Eppenhuizen (where Tryntje was born).  This definitely narrowed the list.
There was one possibility that stood out.  Something about it was summoning me.  It just "felt" right.

I stumbled upon an indexed listing for the following:

Marriage: 17 Aug 1787 at Groningen
Bridegroom: Jacob Lovers of Groningen
Bride: Trijntje Hindriks of Eppenhuizen

Could this be her?  Was this Jacob's sister??

Digging deeper, I found the following...

Tryntje Hindriks and her husband Jacob Lovers (misspelling) were married on 17 Aug 1787 at the famed Martini Kerk in Groningen.  Here's what's interesting about this record... HINDRIK ROSEBOOM.  Hindrik is listed as Tryntje's stepfather.  He wed Tryntje Hindrik's mother, Tryntje Sybels, earlier that year.  His name confirms the record.

But Lovers.  That name didn't sit right.  Too English.  Lovers is not a Dutch name.  And of course I found no indexed names under Lovers.  Another roadblock?  Only a minor one.  As Jacob (Lovers) is listed as being from Groningen (the city), I checked the Groningen Church Registry for Jacob. 

Here is our guy... the husband of Tryntje Hindricks.  And according to the above record, Tryntje was not his first wife.  He had been married before - in November of 1776 - 3 YEARS AFTER the birth of Tryntje.  Yes, Tryntje married a man 32 years her senior!

His true name is Jacob Laufer.  He was the son of Abraham Laufer and Tryntje Simons and was born on 28 November 1741.  The record lists the children as:

Tryntje - ?
Abraham - born 27 May 1782 (with first wife Itje Jans)
Abraham - born 10 May 1788 (first child with second wife Tryntje)
Hindrik - born 8 June 1790
David - born 28 April 1792
Tryntje - born 4 April 1794
Annigje (not listed) - born 10 Nov 1803

Jacob Laufer died 11 Dec 1806.   What happened to Tryntje?

Tryntje's son David married Jan Renjes de Graaf on 18 May 1826 at Leens.  Part of the documents required for marriage included the death certificates of any parent of either party who was deceased.  The following record was part of this requirement.

Trijntje Hindriks died 30 Sept 1825 at Groningen.  Interesting too to note that the above record states that Trijntje remarried. 

Tryntje married Hindrik Jans (ironic... I know - same name as her father).  They married 27 Sept 1807, less than a year after the death of her first husband.  But this is NOT the name we find recorded on her death certificate.  Why?

Remember that in 1811, Napoleon, who for a short time ruled the Netherlands, mandated that all families must choose a surname.  Up to that time they used patronymics.  So the name recorded - which appears to be HOET (I think this is probably meant to be HOEK) - is likely the name chosen by her second husband.

More information pending....
