Gerard was the king of Kovir and the son of Gedovius and Gemma, as well as the last of the House of Troyden. He had five children: Anna, Alicja, and three unnamed sons but they all tragically died except for Alicja.

He granted young Guido Thyssen a favor by giving him a title of the Margrave of East March and, later, giving the hand of his youngest daughter Alicja to Edmund Thyssen.
