Born near Niles, Michigan, his family moved to Broken Arrow. Oklahoma, in 1907 in a boxcar. The family later moved to Tulsa in 1910. In 1927 Larkn’s father, W.S. purchased the Tulsa Abstract Company and later purchased a second similar company.
Larkin graduated from Central High School and decided to lie about his age and join the U.S. Marines. As Corporal Bailey he served in World War One, earning distinction in the tough battle of Belleau Woods. All his life he was loyal to the Marine Corps living by the code "Once a Marine always a Marine." A measure of the Marine’s love for their oldest member in northeast Oklahoma, the local Tank Tow Company volunteered to act as pall bearers at his funeral and appeared in full dress for the service at First Presbyterian Church.
After the war, Larkin attended several universities including T.U., California at Berkeley, Yale and the University of Iowa. Another loyalty was that of a member of Sigma Phi Epsilon fraternity. For many years he led the alumni as a fraternity officer.
An excellent athlete, Larkin lettered in baseball and football. He loved baseball hoping to play professionally. After a short stint with the Chicago White Sox and the Detroit Tigers he gave it up to study for his law degree. In later years he scouted for the St. Louis Browns, the Brooklyn Dodgers and the Milwaukee Braves from 1937 to 1955.
Larkin took over the abstract business when his father retired in 1936 and its operation became his life until he could no longer make it to the office. His canny business knowledge led him to purchase and profit in many ventures. The most important was the purchase of 2500 acres near Owasso where he raised pure bred Angus cattle. Today the cattle are gone and the land is in the Bailey Trust. Some has been sold for a golf course and a housing development.
Another of his interests was his charier membership in the SPEBSQSA - a national barbershop singing organization. He promoted the organization of the Owasso Rotary Club and the Sunrise South Breakfast Club. Because of his generosity he offered matching funds to members of his Rotary Club to support a number of Paul Harris Fellowships.
In 1939, Larkin married a school teacher, Elsie Schlegel. Larkin and Elsie were blessed with a daughter; Florence Ann, and a granddaughter, Gretchen Caraway.
