Heren van Raaphorst

In De Nederlandsche Leeuw 1983, Van der Klooster sets out how Van Leiden, Van Wassenaar and Van Raaphorst sprote from Doede van Voorhout through his son Kerstant. John Ooms gives us at line of descendance. Who do we find if we search the Groesbeek Collectie (GC) and Oorkonden (OHZ)?
