Oscar Mayo was born on January 25, 1851, in Pennsylvania. He was the son of Raymond H. Mayo and Hannah S. Underhill. An industrious man who was a Stone Maison and dairy farmer. He was counted twice on the 1870 census, with his age given as 17 in both records. He was listed in his parents’ home in Terry, Bradford County, Pennsylvania, with two younger brothers and a younger sister, and he was listed in the home of Simpson Underhill in Dimock, Susquehanna County, Pennsylvania, probably a relative of his mother. He married Lycenia Strong, who he outlived by ten years after raising four daughters and one son. Lycenia died in 1927 and Oscar died at the age of 86 on September 9, 1937.


Note: PA Death Index gives his age at death as 66. This is a transcription error, as confirmed by his actual death certificate.


Note: While researching Oscar Mayo (1851-1937) of Pennsylvania, it is sometimes difficult to distinguish if a record is referring to him or to Oscar G. Mayo (1854-1942) of Broome County, New York. Aside from the obvious similarity – sharing the same very unique name, their lifespans were remarkably parallel and they lived within about 50 miles of each other all their lives. In most records, it is easy to distinguish between them because Oscar & Lycenia Mayo lived in Pennsylvania most their lives, but in 1920, they temporarily moved to New York. On the 1920 census, they were counted on the census in a home they reportedly owned in a town called Maine, Broome County, New York. 11 miles from Oscar G. Mayo, who lived in Binghamton at the time.


Oscar Mayo & Lycenia Strong were the parents of my ancestor,

  • Lydia (Mayo) Decker

  • Eliza Mayo (1874-1888)

  • Lucy P. (Mayo) Hunt (1876-1957)

  • May C. (Mayo) Lewis (1880-1938)

  • Alvin Mayo (1883-1958)
