Erfgoed Fundaasje

Heritage Foundation ensures that your archives are saved. We track down, save, and make an inventory of family and company documents, and make them publicly available.



In the St. Jacob’s Church of St. Jacobiparochie from 10 July until 10 September there are three exhibitions of cultural journeys:
1 an expedition through the clay ceramics and also drawings of Ryt Kooistra
2 a pilgrimage of Saint James from St. Jacobiparochie to Santiago de Compostella
3 a walk through heritage, excavated from the clay of Het Bildt and secured by Heritage Foundation.

Church is open on every Saturday from 13.00-16.00.

Heritage Foundation has digitized another old photo album and along with it set up a genealogy. It concerns the family of Jelle Dooitzes Nauta from Bitgum. Of most portraits it is unknown who they are. Who can help?

The Heritage Foundation will again work with Tresoar in 2021 if it is up to the foundation. The two institutions have had a fruitful cooperation agreement since 28 October 2016, but this was severed in June 2018 by Tresoar.

Heritage Foundation wants to continue this collaboration when a new director joins Tresoar this year.

Heritage Foundation has an agreement with the Municipality of Waadhoeke regarding the future security of agricultural business and family archives. Those archives have been opened for investigation. See also: About us.

It is obvious that the community property that falls outside the boundaries of Waadhoeke will be housed at Tresoar, in accordance with its core tasks.


On 23 December 2020, Sake Meindersma and Gryt Meindersma-de Boer in Burdaard donated their Sinnema Collection to the Heritage Foundation, which includes photos, mourning cards and other documents from the legacy of Gryt Sinnema.
Here is a photo of Gryt Sinnema’s mother and aunt Gryt and Pyt Boschma and the mourning card of her great-great-grandfather Hendrik Louws Palsma. It is of value that even such letters of condolence are preserved, do not throw them away!

A design from 1953 has been added to the Brouwer-Bitgum Collection for a tile panel by N.V. Tichelaars Kleiwarenfbriek in Makkum (Royal Tichelaar, 1572)

The painting was probably intended for a new house by potato farmers Arjen Gerbens Brouwer and Yke de Jong, pioneers in the Noordoostpolder, but it was never completed. The drawing in black pencil is 65 cm high and 39 cm wide. Central is the tree of life, in the middle of which is a village view with a church and a head-neck-body farmhouse with a plowing farmer in the foreground, behind a single-furrow plough pulled by a two-man team. In addition, a sailing barge.

At the bottom of the tree trunk is described in Art Nouveau letters: Psalm 24:2; and in the roots to the left: The earth is the Lord’s, and to the right: He has founded it upon the seas. On the bottom is an open bible with the text: To the one who is victorious, I will give the right to eat from the tree of life. Rev. 2:7

Had this panel been completed, it would have had fifteen tiles of 13 x 13 cm.  Three in width and five in height, including the rim.
The drawing is not signed. It is possible the maker is Jan Romkes Steensma (Purmerend 1887-Sneek 1967; x 1918 Tjitske Steringa), who had been working as a pottery painter at Tichelaar in Makkum since 1907.
See: P.J. Tichelaar, Fries aardewerk – Tichelaar Makkum 1868-1963, Primavera Pers, 2004, ISBN 9789074310901, page 213). Thanks to Pieter Frietema of Royal Tichelaar.


A collection of designs in black pencil and poster paint for cealing and wallpaper decoration has been added to the Hellema Collection. The pencil drawings were made in 1913 by M.J. Steenstra. On display are Art Nouveau patterns with floral figures and birds. One design depicts the Great or St. Martin’s Church of Hallum.


Hannelshûs Hettema was founded in 1898.
According to family tradition, it was founded with the name Handelshuis Hettema or Hettema Aardappelhandel and is founded on 27-2-1898. This is the birthday of Hette Hettema, he will then be 35 years old (* Bitgum 27-2-1863). However Hette Hettema has also previously traded in mainly farm potatoes – including Germany.

When sons Tjitze and Fokke join the business, the name becomes Firma Hettema Zonen.
In 1999, Hettema Zonen merged with the ZPC under the name HZPC.
HZPC, the Hettema family and Erfgoed Fundaasje would like to find out if there is any evidence about its foundation in 1898, because we do not have any available so far. Does anyone have such documents? These would include deeds of purchase, photos with dates and old accounts.


In the old Town Hall in Franeker (Riedhúsplein 1) a permanent exhibition of the work of Erfgoed Fundaasje has been set up, in collaboration with Historisch Centrum Franeker and the Bildts Aigene. Below is an overview with text and photos.

Viewing by appointment: 058-212 00 35.

Donation Zijlstra Collection,
Zijlstra Genealogy


Family of the president of De Nederlandsche Bank (The Dutch Bank)
On 1 August 2020, an archive of the farmer’s family of prime minister Jelle Zijlstra was donated to Erfgoed Fundaasje. This business and family archive had been kept for a long time on the Sylstra farm in Klooster-Lidlum, south of Oosterbierum, and came into possession of Thea Brandsma-Zijlstra because her family was the last to work on her ancestors’ farm.
This archive is very valuable because the family has kept the business accounts nearly without gaps from the end of the 19th century until the 1990s.
Further work is being done on this inventory and will be completed eventually.


What is Charlemagne doing here? Nearly everyone in the Abendland (the western world) has blood coarsing through their veins of this bully and at the same time Father of Europe. As such, he also has a place in the pedigree of Goasse Goasses Offringa, as the umpteenth person, namely number 570,270,302,208. What does that say of ‘high’ descent? If you calculate that the number of ancestors per generation is doubled, then in the time of great-grandfather Charlemagne, theoretically you’d have 570 billion ancestors, and at around 800 AD, Europe had a population of only about 35 million.

So relative, and at the same time so close. For instance, if you are interested, click number 8,701,634 in this pedigree: Floris V count of Holland and Zeeland, ‘Der keerlen god’ (God of the peasants) and ‘‘Hear’ fan Fryslân’ (‘Lord’ of Frisia), at least, so he calls himself; or Mathilde Plantagenet and all of her ancestors, number 139,226,153. And if you have gotten a taste for it, there is also number 17,820,946,945 Gorm den Gamle, the Old, the first king of Denmark. Well, anyway. Others will do research up to Adam: Offringa: From Adam To Esther
