Boudewijn van Offenberg or Offenberch (1590–1653), was a Dutch Golden Age notary, merchant and member of the Haarlem schutterij.
[1] Boudewijn's mother Maria van Loo and his uncle Dirck van Offenberg were the godparents of Dirck Hals in Haarlem, but the families knew each other already from their Antwerp period, because the sister of Boudewijn's grandmother Maria van Offenberg had been the godmother of Maria Hals, the older sister of Dirck and Frans, who was born in Antwerp.
[1] He married Beatrix de Laignier in 1627 and was a merchant in Haarlem, Leiden, and Bad Bentheim.
[1] After they married they lived on the Spaarne at the spot where the house number 47 exists today.
[1] The disease elephantiasis was rare, so it is possible that he was just fat, as his second portrait by Hals shows him to be considerably fatter than the first, though he was only 37 at that time.
