Families covered: Bentinck of Portland

Hans William Bentinck, 1st Earl of Portland (b 20.07.1649, d 23.11.1709)
Hans William was the 4th son of Bernard, Baron Bentinck, of Diepenheim, etc in the Netherlands. According to BP1934 (Portland), he was "page of honour, and subsequently confidential adviser of William, Prince of Orange (and) accompanied his royal master into England". BP1934 provides a pedigree of the Earl which we omit on the grounds that, being non-British and non-royal, it is outside of the scope of this database. However, we may review that decision in due course.
