In his capacity as a royal favorite and agent of the king, Hopkins acquired lands for ranching at Kahuku on the windward side of the island of Oahu from the royal crown lands. The Euro-American community, especially the American Protestant missionaries, disapproved of Hopkins close association with the Hawaiians and his private life. Hopkins had a son Charles Louis Kamohoalii Hopkins (1853–1918) out of wedlock with a Hawaiian woman. The woman and her husband were working as servants and living with Hopkins at the time.
