My name

According to Dutch naming traditions Coen should have been named Cornelis after his grandfather, but his parents decided it was too old fashioned. It did upset the grandfather for a bit, but he came around in the end and named a boat after him,

Cornelis Dijkgraaf (1908-1993) on the boat Coentje

For the origins and meaning of the Dijkgraaf name see the Dijkgraaf Name Study

I'm fluent in English, and get by in Dutch as I didn't speak or read it much for quite a few years since I was ten, but doing genealogy has improved it a bit again. Sometimes to translate to or from Dutch I will use Deepl.com or Google translate

Hi Coen, could I get you to do a quick check of the categories on a profile after saving, after adding the Netherlands sticker? It adds a category and if it's not exactly right it adds an incorrect red category to the profile. There's been a few recently. Many thanks, regards, Margaret

Hallo Coen Jacob Dijkgraaf zou jij de PPP van Jetses-22 willen af halen, zodat deze kan worden gemerged in Jetses-16.

Bedankt

Hi Coen,

I saw you every once in a while adding people born in Northrhine-Westphalia and married in the Netherlands to Category: Germany, Needs Birth Record. Maybe you also want to add them to a migration category like Category: Prussia, Emigrants to the Netherlands?

Kind regards

Flo
posted by Florian Straub
Hi Flo.

I'm not that familiar with German history, so I don't know when (for which time period) the category would be appropriate. Feel free to add them to the appropriate categories, or to update the categories if I haven't picked the right ones. It is a collaborative tree after all, and by me adding the Needs birth record, then it comes to attention to those that can update it.

Hi Coen,

By the way: the Migration Category Helper of WBE now also supports Dutch provinces.

Kind regards from Black Forest

You stated "Dutch women don't take on husbands name". That's a mistake. Lots of women still do that, although this is no longer an obligation as it was in the past. Nowadays if you are married or have a registered partnership, you may use your partner's surname. This concerns the daily use of your partner's surname. You can register this name (or have it registered) with your municipality in the Municipal Personal Records Database (BRP). You do not need your partner's permission for this. The Tax and Customs Administration, your health insurance company, and other authorities will write to you using the name you have chosen. Your official surname will not change as a result. Official documents always state your official surname. For example on your passport or driver's license.
posted by Ed Visser
Yes, but the profile I made that comment and pre-dates women being legally being able to take their husbands name in the Netherlands. Yes, they may have been informally known by their husbands name, but as you stated, it won't be their official name. So it should not be their Current Last Name, but possibly under Other Last Name

Hmm, looks like Dark Mode hides that link red link, as they all turn green. I'll have to see if I can fix that in the Browser Extension.
