Zoek mee in jouw stamboom naar #patrijskinderen: voorhuwelijkse kinderen die later ‘gewettigd’ werden door een ‘vader op papier’.

Nieuw citizen-science onderzoek!
Dacht je dat men vroeger altijd wachtte met kinderen tot na het huwelijk? Zeker niet!
In de 19de eeuw kreeg in Vlaamse steden tot 𝗲́𝗲́𝗻 𝗼𝗽 𝘃𝗶𝗲𝗿 𝗺𝗼𝗲𝗱𝗲𝗿𝘀 haar eerste kind vóór het huwelijk.
