I heard this name before when I saw that name on the Hockaday school history, I needed to learn more. My grandfather is his illegitimate son. His name was John Wesley Adams. He was born in Hearne, TX in 1894. Horatio was his father and Maggie Mayes was his mother.
During the time when my grandfather, John Wesley Adams, was living a lot of light skinned blacks moved to the north and passed for white. He refused to do that as his pride would not let him do it. He never spoke about Horatio at all and from what I remember, Horatio did reach out to try to pay for college. My grandfather refused his help. John Wesley Adams retired from the railroad around 1958.

After further digging, I traced his grandfather's name as Horatio Rearden Hearne and I traced the Hearne family name back 8 to 10 generations to Somreset Maryland to London England in 1627.
I can trace the white generations of my family but it's difficult to trace the black part because of slavery.
