Willem van der Haegen, at times Willelm van der Hagen or Willelm van der Haagen (Flanders, Bruges or Maastricht, 1430 - Topo, S o Jorge, 1510), transliterated to the Portuguese as Guilherme da Silveira (another variation on his name is Guilherme Vanderaga), was a Flemish nobleman, entrepreneur, explorer and pioneer in the settlement of the islands of the Azores.

In 1454 he married Margarida de Zambuja in Bruges, Flanders (at times referred to as Frutuoso de Margarida da Sabuya, others would refer to Margarida da Sabina, Sabuia or Margarethe Sabuio) and would father eight children which would all integrate into the communities of the Central Group of islands:
- Luzia da Silveira (Bruges, 1464 - Topo, 1548); married Andr Fernandes Villalobos (1485) in the villa of Topo, S o Jorge;

Settlements in the Azores
As part of his inheritance, King Edward of Portugal bequeathed the islands of the Azores to his brother, the Infante D. Henriques (Henry the Navigator), in 1433. This was subsequently left to Henry's nephew and adopted son, Infante D. Fernando, in addition to Henry's title as Grand Master of the Order of Christ. A grant was made by the Infante to his aunt, D. Isabella of Portugal (Edward and Henry's sister), the Duchess of Burgandy, in the Low Countries. For many of the Flems who were recuperating from the Hundred Years War, this grant offered an opportunity of alleviating their suffering.
Van der Haegen, a wealthy entrepreneur, was invited by Josse van Huerter (for four-years Captain-General of the island of Faial) to settle the island with him, in an archipelago that was becoming known as a New Flanders or the Flemish Islands. Consequently, in 1470, with his wife Margarida da Zambuja and at his own expense, he offloaded two ships carrying his extended family, slaves and professionals of various services, to began what was characterised as a "second-wave" of immigration to the island (the first having been pioneered by Van Huerter in the 1460s). Van der Haegen, by his virtues and distinguished personality, became popular on the island. But, sensing a level of bad faith on the part of Huerter and a growing rivalry, he abandoned his holdings on Faial, to settle in Quatro Ribeiras, on the island of Terceira. He begins to cultivate wheat and gather woad plants for export (specifically Isatis tinctoria which was also produced in the Picardy and Normandy Regions of France until that time). These plants, along with other species, were essential in the production of many of the dyes popular with mercantile classes. Most islands in the archipelago were populated, and the plants commercialized by the landed gentry for their exportable nature; early settlements were founded on the basis of agricultural and dye-based exports, such as woad. Van der Haegen's colonies were no exception.
On a trip to Lisbon he encounters D. Maria de Vilhena (widow of D. Fern o Teles de Meneses, the Donatary of the islands of Flores and Corvo, then administratively one fiefdom) and his son Rui Teles. After some negotiation, D. Maria would cede the rights to the exploration of the islands to Van der Haegen, in exchange for monthly payments. Around 1478, Willem van der Haegen settles in Ribeira da Cruz, where he built homes, developed agriculture (primarily wheat), collected more woad species for export, and explored for tin, silver or other minerals (under the assumption that the islands were part of the mythic Ilhas Cassterides, the islands of silver and tin). Owing to the island's isolation and difficulties in communication his crops became difficult to export. After several years, he decides to leave the island and return to Terceira. But, his return was brief; after seven years he leaves Quatro Ribeiras and settles in the area of Topo, S o Jorge Island, effectively establishing the community with other Flemish citizens. He died in 1500, and was buried in the chapel-annex of the Solar dos Tiagos, in the villa of Topo, today in ruins.
The Flemish surname Haag means forest, which is translated into Portuguese as Silveira. The families with the surname Silveira, generally, descend from the Fleming Willem van der Hagen, although there is a branch of Silveiras on the island of Graciosa that are direct descendants of continental Portuguese families. Van der Hagen by his virtue and personality was able to found settlements that would eventually develop into important communities in the Azores. His descendents, using the adopted name Silveira, would continue his work on the islands and within the Portugues empire (to a lesser extent). The name Silveira was adopted by Van der Haegen during his life in the Azores, from the literal translation to the Portuguese of the Dutch Haag or Haeg meaning "bush", "forest" or "scrub", which is silveira in the Portuguese. His family lineage is separate from the Silveiras of continental Portugal which also inhabited some settlements in the Azores. Van der Haegen obtained from King John II of Portugal, confirmation of family heraldry (used in Flanders) for his use in the archipelago.
