Research process

At the beginning of the 17th century some people bear the family name Van Bohe(e)men. They live in the former manor of Monster and the western part of the former manor of The Hague. The most known of them is Dirk Jansz. van Bohemen who lives on a farm near the hamlet of Eikenduinen. Hence this farm gets the name Bohemen. During World War II it is demolished due to an expansion of the city of The Hague. However, the existence lives on, because the concerning new residential area of The Hague is called Bohemen.

Archive research in 2017 has cleared up how the first persons with the family name Van Bohe(e)men are related to each other. The earliest ancestor identified is seen as the founder of the family Van Bohe (e)men (until a still older ancestor is found). The results of the archive research have been published in two articles by Peter J.M. van Boheemen in the Dutch periodicals Gens Nostra and Ons Voorgeslacht  (see Publications).


The oldest ancestor about which reliable information has been found, is Sijmen Jan Philipsz (ca. 1500-ca. 1560). He lives in 1544 on a farm in the Lozerdijkse Polder (later Uithofpolder), lying in the former manor of Monster . This farm gets the name Vrederust, but this happens probably much later.

Sijmen Jan Philipsz. owns Vrederust, including the parcel of 6 ‘morgen’ on which the farmyard is located (1  ‘morgen’ corresponds with 0,85 ha). Beside he leases 67 ‘morgen’ land, of which 7½  ‘morgen’ from the parisch charity Heilige Geest (Holy Spirit)) in The Hague. The  concerning 7½  ‘morgen’ lies in the Escamp Polder which borders on the northeast side of the Lozerdijksepolder.
The extensive land use indicates, that Sijmen belongs to the upper layer of the rural population.

In view of his patronymic, Sijmen is a son of Jan Philipsz. This will be Jan Philipsz, who leases in 1518-1522 land from the above mentioned Heilige Geest in The Hague. This lease concerns three parcels covering together about 7½ ‘morgen’. This is the same area as leased later by Sijmen.
The lease of 7½ ‘morgen’ to Jan Philipsz. begins in 1486. ​​Previously the parcels are leased to Sijmon Hubrechtsz, possibly a relative of Jan Philipsz.

Furthermore, both Jan Philipsz. and Sijmen leases 3 ‘morgen’ from the Abbey in Loosduinen.

The grandfather of Sijmen Jan Philipsz will have Philip as his first name. He will be born around 1430. For the time being this Philip is considered the founder of family Van Bohe(e)men.

Possible earlier ancestors

The similarities in land use suggest that Jan Philipsz, the father of Sijmen, also lives on Vrederust. This may also be the case with earlier ancestors of Sijmen. That’s why there has been looked at a survey of the manor of Monster executed in 1378. In this survey not only the areas of the parcels are recorded, but also their owners and users.

In the southern part of manor part VII, where Vrederust is located, a parcel of 6 ‘morgen’ is recorded. This parcel is owned then by Sijmen Florisz and used by Gielis Sijmonsz. It is quite possible that it concerns the same parcel of 6 ‘morgen’ which Sijmen Jan Philipsz has in possession in 1544. About a residence on the parcel is not spoken.

At the time of the survey a parcel of 29 ‘morgen’  lies near the parcel of 6 ‘morgen’. Part of 24 ‘morgen’  is used by Gielis the Younger. Thereby Gieles Sijmonsz will be meant.

The different land use data have led to the hypothesis that founder Philip is a grandson of Gielis Sijmonsz. The father of Philip may have named Sijmen Gielisz. A yet unknown source can prove whether the hypothesis is correct.

The aforementioned assumptions have been incorporated into the following hypothetical geneagram.

Sijmon Huijbrechtz is also inserted in the geneagram. He is mentioned above as leaser of land of Heilige Geest in The Hague. Perhaps he is a cousin of Jan Philipz.

Sijmen Florisz may also have a son Floris Sijmonsz. On July 13, 1401, more than 2 ‘morgen’ in Monster is sold to the abbess of Loosduinen. Thereby Floris Sijmonsz is mentioned as a neighbour. On the basis of the survey from 1378 it is presumed that the parcel in question is located near the farmyard of Vrederust.

The genogram still has limited evidence. Therefore reactions are welcome.

However, it is also possible that founder Philip is a son of Jan Philipsz mentioned in a charter from the year 1431. This document concerns an exchange of parcels which Jan Philipsz and Willem Jansz own on both sides of the Hollewatering, north of the Gantel. The Hollewatering is an extension of the Wennetjessloot which forms the eastern border of the Lozerdijkse Polder (see map above of the manor of Monster).
