George Charles Mo'oheau Kauluheimalama Beckley (May 5, 1849 – July 4, 1910) was a member of Liliʻuokalani's Privy Council of State from 1891 to 1892, and a director of the Wilder Steamship Company.

[4][5][6] His maternal lineage descended from Kameʻeiamoku (died 1802), one of the royal twins (with Kamanawa) who advised Kamehameha I in his conquest of the Hawaiian Islands.

[4] Beckley's mother Kahinu was the daughter of Hoʻolulu who, along with half-brother Hoapili, helped conceal the bones of King Kamehameha I in a secret hiding place after the ruler's death.

[2][9] In 1897, Mary was mentioned in an article by Janet Jennings, of the Chicago Times-Herald, about the important role and status of part-Hawaiian women in the Hawaiian nation, which described her as "one of the most graceful young matrons in Honolulu.

[13] The last eight years of his life, he was referred to in the news media as "Admiral Beckley", but the title was honorary, not an official career rank.

On January 18, 1902, the Masters and Pilots Association labor union of Honolulu had an "admiral's flag" designed as a gift in recognition of his lifetime working on the seas.

[14] Beckley set his sights on a career at sea at an early age, and hired on as a cabin boy aboard the whaling bark Catherine.

Beckley himself at times had selective memory about his accomplishments, once claiming to have discovered the North Pole and also to have struck gold in Nome, Alaska, both in 1863 during voyages with Captain Alfred N. Tripp.

[19] The Hawaiian government became the sole owner of the Kilauea in 1870, and Beckley signed on as a deckhand in 1871, at that time under the management of Samuel G. Wilder.

[16] He was listed as the commodore for the Wilder Steamship Company Helene on her 1897 maiden voyage from San Francisco to Honolulu.

[28][29] Beckley was a seafarer, not known for political involvement, but his ties to the monarchy, and his loyalty to the native Hawaiian population, impelled him to run for office.

It also raised property requirements for suffrage, disenfranchised many impoverished native Hawaiians and naturalized Asian citizens, and gave the vote to unnaturalized foreign residents of European or American descent.

Instigators of this coup d'état formed the Reform Party, drawing its membership from Hawaiian conservatives and citizens of foreign descent.

[16][36] He was appointed to the Privy Council of State of Queen Liliʻuokalani on August 31, 1891,[37] and sworn in by Chief Justice Albert Francis Judd on July 8, 1892.

[3] Wife Mary Beckley and daughter Juanita accompanied his body back to Hawaii on the Matson Navigation liner SS Wilhelmina.

[41][42] He was a 32nd degree Mason, and when the SS Wilhelmina arrived in Honolulu, six members of masonry lodges in Hawaii escorted his body to the Beckley home, where friends and family paid their respects.
