Life with Boswell:
A Count d'Ouwerkerke was mentioned by Boswell on November 26, 1763, when Boswell met him at the Countess of Nassau Beverweerd's. He wasn't identified for certain at the time of publishing of Boswell in Holland, but there seems little doubt that Lodewijk Theodoor II is the person Boswell referred to, i.e. he was adopted by the Count of Nassau Beverweerd, where Boswell met him, and was styled Heer van Ouwerkerk from 1762 to 1773.
Boswell described him as "lively, good-humoured, and quite a little man of the world." Later on, in conversation with the Count's sister, he told her that "Your brother was my good friend. He taught me all the etiquette. He is always gay. He speaks French well. He speaks very fast". (December 21, 1763)
