(1) Cornelis Albertsen was a very common name in Amsterdam at that time. They can be told apart by their different professions: a master, a miller, a singer and a man called Cornelis Alberts who carries beer are very active in that periode of time. That is why we do think the Cornelis Albertzen (with a profession as "lichterman") who on 28 december 1641 buys a barge with the name De Jonge Bestevaer is Willempie's father (please consult notary Jacob Jansz Westfrisius in the stadsarchief of Amsterdam). 

(2) This is how the notary wrote their names. They themselves noted their handwritings benaeth the document as Willem Hesselze Vlamingh and Willemtie Cornelis.

(3) Please consult: Kwijtscheldingenboek in stadsarchief of Amsterdam on juni 6, 1687.

(4) In the deed about the previously mentioned bonds from Willempie's father (on December 5, 1672 with notary Salomon van der Sluijs) we read something about a certain Wibo Olofs, skipper on the ship Hoff bij Dantzich, who also lived on the Lindengracht. This strengthens our suspicion that Willempie's parents lived on Lindengracht for at least the last part of their lives.

(6) See in the notarial archives of the city archives in Amsterdam the deed of 14 May 1725 with notary Arnoldus Commelin (5075, inventory number 8560, scan 73-75) and also the will of Clara Heems on 6 June 1712 (5075, inventory number 6328 , scan 229-232).

(7) See the deed of March 24, 1642 with notary Jacob Jansz Westfrisius (Amsterdam City Archives, 5075, inventory number 525, scan 79).

(8) See the so called Schepenkennissen of June 10, 1632 (Amsterdam City Archives, 5063, inventory number 29, p. 47 (= scan 49 and 50).

(9) This transfer appeared in the books on November 28, 1635. See the so called Kwijtscheldingenboek (5061, inventory number 2166, scan 230).

(10) A biersteker is an old Dutch word nobody uses anymore. In the past, beer from the brewery was bought up by such a middle man and sold on to the innkeepers.

(11) Please consult in the Amsterdam Stadsarchief the deed of June 22, 1690 by notary Simon van Sevenhoven: archiefnummer 5075, inventarisnummer 5260, pag. 633.

(12) Later we will encounter this Alof Pietersz again as he sells his half of a house to Willem and Willempie  (the first half is already theirs, please consult the socalled transportregisters of Vlieland on May 21, 1681). Alof, who was described as the island's court messenger at the time of the sale, was probably once their neighbour or at least the owner of part of the house in the Groote Straat where the De Vlamingh family lived.

(13) Oost-Vlieland is the name of the village in the east of the island. In that time there was a village in the west too, not very creatively called West-Vlieland.

(14) Thanks to the books De lage zijde written by Ben Stenekes and Jan Houter (Flevodruk Harlingen, 2016), and De Hoge Zijde van Beam Duurentiidt (which is the pseudonym of Ben Stenekes) from 2005.

(15) The only Foppe Obbesz we encountered during our research was married to a lady called Neeltje Willems. There were several women on the island at that time who were called Neeltje Pieters and one gave a house in the Groote Straat as collateral on December 22, 1696. The house is on the North side, west of the house of Willem Vlaming. So maybe this is their neighbour, but that conclusion is not certain.

(16) Unfortunately, we are not totally sure this passage is about our Willempie, because there were more women on the island at that time who bore the name Willempje Cornelis!
