Well! Those van Tullekens did get around!

Just found this in the 1741 baptism register for South Leith (so Edinburgh really):

Isabel Pringle late servant to Mrs Walls had in Fornication, as she says, to Captain Tuliken, A.S.N. [A Son Named] Andrew, Born 7 & Baptized 23 July 1741. Sponsor Andrew Wright Weaver Indweller in Leith, Witt[nesses] Robert Robertson & Francis Thomson Indweller yr [there]

The twins' Who Do you Think You Are did say the family were seafarers, and Leith is just across the North Sea from Amsterdam, so I bet it is the same family – even if distantly.

I'd say almost certainly part of the same family. The old parish records are brilliant with their "base born children" and "fornication".

Aren't they just!

The Scottish church sessions are determined to identify the father – by which he become financially responsible, I think. The sessions rebuke the parents, but accept the children.

Then there are the irregular marriages recorded in the church registers after the fact.

It's all very helpful for the historian!

Yes it’s all about making the father pay. Which isn’t a bad thing, but how they’d force a Dutch sailor to support a child in Edinburgh us another matter.

They really do. I work in the south of the Netherlands and have a client of that name

Have you noticed it being a common name in the Netherlands, Owlbasket?

Not particularly, but I’ve come across it a few times. I’m right down near the Belgian border pretty much as far away as possible from the traditionally seafaring area

There was a programme where the Van Tullekan twins investigated their family and they did come from Dutch aristocracy ( their ancestor pushed for recognition).
An ancestor was heavily involved in the slave trade. This upset and I think,shocked them.
At their family home were interesting artefacts that they never thought to ask their parents about 😮
