Principality of Sealand
Brimeyer's first attempt to ennoble himself came when he named himself, "Brimeyer de la Calchuyére", in the 1950s when he was about ten years old. This came to nothing. In 1955, he took a name, "His Serene Highness Prince Khevenhüller-Abensberg", but the real Princess Khevenhüller threatened to sue him. He backpedaled and apologized. Brimeyer also wrote to a number of aristocrats to convince them to adopt him. In 1969, he received a passport of the Principality of Sealand with the name "His Highness Prince Alexis Romanov Dolgorouki". When he contacted a Brussels Orthodox priest, Jean Maljinowski, to be baptized, the priest was suspicious since the supposed prince did not speak a word of Russian.
