Alfred Wellington Carter was born April 22, 1862, and named for an uncle Alfred Wellington Carter. Another uncle Henry A. P. Carter had been a cabinet minister and diplomat for the Kingdom of Hawaii. His uncle Joseph O. Carter was Liliʻuokalani's legal advisor and served on her Privy Council of State. Since many of his relatives were also named Alfred, he went by his initials "A. W."
In 1899 Carter was appointed guardian of Annie Thelma Kahiluonapuaapiilani Parker, heir of half of the vast Parker Ranch founded by her great-grandfather John Palmer Parker. He moved to the island of Hawaii and became manager of the ranch, although his wife stayed in Honolulu where the children attended school. Carter was often at odds with the other half-owner, Samuel Parker, who wanted to use income from the ranch to fund his lifestyle instead of expansion. Parker sued, claiming he owned the entire ranch, and tried to remove Carter as manager. The court case dragged on for years. Carter mortgaged the ranch and bought Parker out in 1906.
