Candidate passages:
Hughes's main interest outside the law was Virginia history and, in particular, the roles played by members of his own family.
He felt particularly duty bound to defend the reputations of two close relatives: Gov.
Floyd, his adoptive maternal grandfather, and Gen. Joseph E. Johnston, his maternal great uncle.
Johnston asked Hughes to write his official biography.
In the dedication to Hughes's volume on Johnston, he wrote: "I take pride in dedicating to the Army of Tennessee, as a tribute to its constancy and valor, this sketch of the Great Captain, who led it in its palmy days, and with whose renown it is inseparably associated."

Born in Salt Lake City, Utah, he was a student at University of California, Los Angeles when he was hired by Hughes.
A member of The Church of Jesus Christ of Latter-day Saints, Gay put together the so-called "Mormon Mafia" that comprised Hughes's inner circle in his later life.
Appointed by the Delaware Court of Chancery, Gay served as trustee of the Howard Hughes Medical Institute from 1984 until his retirement in 2006.
He had previously served on the Institute's executive committee from 1971-1984.

Gay died in Kingwood, Texas. 
In his early writing, including "The Negro Speaks of Rivers", Hughes was inspired by American poet Carl Sandburg.
Like many of Hughes's other writings, the poem depicts an African-American who recognizes and reaffirms his connection to Africa and uses that African heritage as a source of pride.
