Question: How old was George II when his daughter was born? Passage:Charles Bertram was born in London in 1723. He was the son of an English silk dyer who was usually accounted to have emigrated to Copenhagen, Denmark, among the retinue of Princess Louisa, a daughter of GeorgeII, upon her marriage to Crown Prince Frederick of Denmark in 1743. (The prince became KingFrederickV three years later.) Other sources suggest the father immigrated earlier, in 1738. The father established himself as a hosier in 1744, and Charles seems to have benefited from the warm reception that Louisa and her retinue received from the Danes. On 5 July 1747, Charles petitioned the University of Copenhagen's Consortium for admission to study history, antiquities, philosophy, and mathematics. This seems to have been granted, although students were generally required to adhere to the Danish Church and Bertram remained Anglican. He became a friend and protege of Hans Gram, the royal librarian and a member of the privy council. On 23 March 1748, Bertram petitioned the king to be permitted to give public lectures on the English language and became a teacher of English in the Royal Marine Academy in Copenhagen. (Some accounts name him as a professor, rather than a tutor; if so, that status would have been granted some years later, as he was a new undergraduate in 1747.) His 1749 chrestomathy An Essay on the Excellency and Style of the English Tongue has been called the initiation of English-language printing in Denmark. A brother apparently died at sea in 1752, and at some point he married Cathrine Marie Gold.
