Possible earlier ancestors

Possibly founder Philip is a son of Jan Philipsz. mentioned in a charter drawn up in 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 Monster amt).

A completely different hypothesis, as shown in Geneagram I, is, that Philip is a descendant of Sijmen Florisz. born around 1320. The geneagram is based on assumptions discussed below.

The similarities in land use discussed above suggest that Jan Philipsz., son of family founder Philip, also lives on Vrederust farm or close by. This may also be the case with Philip and some of his ancestors. That’s why there has been studied a survey of the Monster amt, executed in 1378. In this survey not only the areas of the parcels in Monster are recorded, but also its owners and users.

In the southern part of amt part VII, where Vrederust farm is located, a parcel of 6 ‘morgen’ is recorded, owned then by Sijmen Florisz. and used by Gielis Sijmonsz. It is quite possible that it concerns the farm yard of 6 ‘morgen’ owned by Sijmen Jan Philipsz. in 1544. The survey does not mention the presence of a residence on the parcel.

At the time of the survey a parcel of 29 ‘morgen’ lies near the parcel of 6 ‘morgen’, of which a large part (24 ‘morgen’)  is used by Gielis the Younger. Thereby Gieles Sijmonsz. will be the one referred to.

The land use data above have led to the hypothesis that founder Philip is a grandson of Gielis Sijmonsz. and a son of still unknown Sijmen Gielisz. Further research must show the correctness of this hypothesis (and the geneagram above).

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

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. It may be, that Floris Sijmonsz. is a second son of Sijmen Florisz.

If Floris Sijmonsz. would be the grandfather of founder Philip,, the following geneagram can be real.
