Ariaantje Abrahamse Jacobs - Ariaantjie's surname?

Ariantjie Jacobsdochter Abrahamse ?
What about her sister born in Madagascar ?

One might also ask why not van Deventer surname change like with her two sisters de Witt and von Mecklenburg .
Still confused with the inconsistency of surname changes when married in South Africa for women on GENI.

The origin of Jacobs is seen in her baptismal record in Rotterdam on 25 May 1673.
Her father's name: Jacob Abramse.

I would also like to see more substantive documentation for the 2 women recorded as sisters on Geni.

In contrast, Wikitree records 3 sisters and 1 brother for Ariaantje - none of whom left the Netherlands. Where is the proof that the 2 sisters on Geni.com were on the ship Berg China as orphans being sent to the Cape?

Gail
Wilhelmina is on the ship it appears look at overview of Ariaantjie

I think my frustration is that statement that she is the half-sister is not accompanied by a source reference. There is no record of Wilhelmina's baptism as there is for Ariaantje's brother and sisters on Wikitree. Where do we see the VOC's list of orphans? Where do we see confirmation that she is the baptized daughter of one of the same parents? What am I missing?

Gail you are not alone.
Also noticed half-sister so one different parent.
See husband of Ariiantjie ;Gerrit Janz van Deventer : last sibling and born in Netherlands others sibkings before him in born USA and parents died in USA

Willemijntjie Abrahamse Jacobs
and
Diana Abrahamse Jacobs
should be names of her sisters

I agree...it really doesn't appear substantiated for any of them

Wilhelmina de Wit, SM/PROG

Diana Bibow von Mecklenburg

Wilhelmina de Wit, SM/PROG

Wilhelmina and Willemyntjie maybe same person ?

If Wilhelmina / Willemyntjie is a sister, with same father, why is she de Wit? Yet she is also called a half sister?

de Witt her father's surname ? Half-sister ?
Where is he?

AN DEVENTER Gerrit Jansz
Written by Stamouers. Posted in V - Z

Gerrit Jansz van DEVENTER het van Veldcamp in Nederlands na die Kaap gekom. Op 29 Oktober 1688 het hy getrou in Kaapstad met Ariaenje JACOBS, sy was "n weesmeisie van Rotterdam. Sy was gedoop op 25 Desember 1670 en was die dogter van Jacob Abrahamse en Heyltjie Ariens.

Ariaentjie Jacobs was een van 8 weesmeisies wat op die Skip Berg China na die Kaap gekom het. Sy was gedoop in die Gereformeerde Kerk in Rotterdam op 25 Desember 1670. Haar vader was Jacob die seun van Abraham en haar moeder was Heiltjie die dogter van Arie. Sy was 18 jaar oud toe sy van die Gereformeerde Burgerweeshuis in Rotterdam na die Kaap gekom het.

Johan van Deventer se navorsing meld dat, "Adriana Jacobs, dogter van Jacob Abrahamse en Heiltje Arijens, is gedoop te Rotterdam in Nederland op 25 Mei 1673. Haar ouer suster Ariaentje wat vroeer algemeen aangegee is as ons stammoeder, sterf op 2-jarige ouderdom en word op 16 November 1672 te Rotterdam begrawe. Op die ouderdom van 5 maande sterf Adriana se vader en op 8-jarige ouderdom sterf haar moeder. Sy word wees gelaat, met die adres Geertruidenberg wat sommer net "den Berg" genoem is. Sy beland in die Gereformeerde Burgerweeshuis in die Goudse Wagenstraat in Rotterdam, Nederland, en word die verkleinwoord Arijantgen of ook sommer Adriaantje genoem. In 1687 besluit die Here Sewentien om weesmeisies van die Rotterdamse weeshuis na die Kaap te stuur as vrouens vir die vryburgers. Saam met sewe ander weesmeisies vertrek sy op Saterdag 20 Maart 1688 vanuit Goere in Holland met die skip "Berg China" en arriveer in die Kaap op Woensdag 4 Augustus 1688."

So regte naam vir haar eintlik Adriana !

Cecilia nou selfde vir haar man a.s b.

Nog nooit iets gesien van Diana Abrahamse as die suster van Adriana Jacobus van den Berg, Ariaentje Jacobs, Arijaentgen Jacobs van den Berg , Ariaantje Adriaansse of Wilhelmina Adriaanse de Wit, of Willemtgen Arijens de Wit. Verskeie alternatiewe name is gebruik sedert hulle op die China gearriveer het aan die Kaap.

Now you see it ( now you don't ) ?

Detlef Biebow, SV/PROG

Dietlof Bibow von Mecklenburg

Diana van Madagascar, SM/PROG

Dieselfde persoon as Diana Bibow von Mecklenburg ?

Private

Her surname is a patronym from her father's first name - Jacob

Removing this relationship, pending sources: Diana Bibow von Mecklenburg
