Inter-Connectedness of All Things

A5. The man in this picture was a Wall Street banker who served as a US Senator in the 1950s and early 1960s. The couple named their second son, born in 1924, after the woman's father, unusually using his full name. What surname, as a result, became the middle name of two US Presidents?

A. Walker, as in George Herbert Walker Bush and George Walker Bush.

Dorothy Walker, who married Senator Prescott Bush, was the daughter of George Herbert Walker. The couple named their second son in honour of his maternal grandfather. George H.W. Bush went on to become the 41st President of the United States, and his son, who also carried the surname Walker as a middle name (and was nicknamed 'Dubya' because of his pronunciation of the resulting middle initial), became the 43rd.
