Jan (I) van Cuijk, heer van Cuijk - titles and name fields

although not my addition, still an explanation why

https://nl.wikipedia.org/wiki/Land_van_Cuijk

he might call himself count, but he did not receive this title, at least there is no information about it

Neerloon is a village in the "heerlijkheid" of Cuyk, so he may also have been lord of Neerloon if he had not lent this portion of his glory to one of his knights

https://nl.wikipedia.org/wiki/Kasteel_Oudenborg

oudenborg castle has been in the hands of Cuyk's house, so here too the title lord is possible.

https://nl.wikipedia.org/wiki/Heerlijkheid_(bestuursvorm)
heerlijkheid is "glory/manor/estate"
heer is "lord,
landlord of a certain area, subordinate to a count (or a higher landlord with more area}; in this case Gelre or Brabant

so as "heer van Cuijk" he was also "heer van Merum en Neerloon" , as they are part of his estate.
I don't know why to state this separately
