George Andrews Moriarty, Jr

George Andrews Moriarty Jr. (1883–1968), called G. Andrews Moriarty in most of his published work, was an American genealogist from Newport, Rhode Island. He was born in Newport on February 14, 1883, the only son of George Andrews Moriarty and Mary Ann Sheffield. His ancestor, John Moriarty, emigrated from Ireland in 1777 and settled in Salem, Massachusetts. George attended St. George's School in Newport, and then did his undergraduate work at Harvard University where he earned an A.B. in 1905, cum laude. He then attended Christ Church at the University of Oxford in England where he specialized in historical studies, following which he returned to Harvard to earn an M.A. in 1907.

Moriarty went to work for the U. S. State Department in the foreign service, and served in consular and secretarial roles in Fiume, Italy; Mexico City; and Guatemala. He returned to Harvard once again to study law, and received his LL.B. in 1916. He practiced law in Providence, Rhode Island and Boston, Massachusetts for over a decade, which time also included a year in the U.S. Army at the end of World War I when he was a captain in military intelligence. In 1927 he ended his career in law and devoted the remainder of his life to historical and genealogical pursuits.
