Although detailed study of F's ancestry is available, a brief summary of the facts appears to be all that is here needed, for the ancestry throws little light on the boy's extraordinary mental ability.
F's paternal grandfather was of Scottish parentage, born in Canada. He was a reasonably successful worker in the printing trade, appears to have been well balanced and socially adjusted, and showed no exceptional traits. He had little education and no special interests. He died of apoplexy at 51 years of age.
F's paternal grandmother, born in Albany, New York, had a public school education (probably). She is still living [[1924]], clerking in a store after her husband's death. She appears to have no special interests outside her home life; is said to be quick and nervous, easily excited, and prone to worry.
F's maternal grandfather was born in New York State, of German parentage. He is still alive [[1924]], at the age of 70, and is very active. His education was limited, but he is an excellent reader and is well informed. He is fond of music, is an active churchman and a choir leader. He is said to be quick-tempered, impulsive, and affectionate. He mixes well with people, and has some leadership qualities. He has always worked as a paper hanger and painter, his business being on a small scale.
F's maternal grandmother was born in New York State; the nationality of her parents is not recorded. She had a public school education. Her interests are limited to home and Red Cross activities. She is friendly and sociable, impulsive, affectionate in disposition, and has a keen sense of humor.
F has several uncles and aunts, none of whom presents any qualities of striking interest. All appear to be normally effective and well adjusted, competent on a small-town scale, enjoying their homes, and taking part in local activities and organizations.
F has one brother, younger than himself, born April 2, 1920. He was given a Stanford-Binet examination, May 13, 1924, by Leta S. Hollingworth, being then 4 years 1 month of age. His Mental Age was 6-0, yielding an IQ of 147. This brother has strong musical inclinations, was a choir boy, and subsequently took instruction in singing.
_Father_. The father of Child F was born in Albany, New York. He had a high school education and business college training. He has always done clerical and office work, especially bookkeeping. He is fond of athletics, reads only newspapers and magazines, is quick, alert, and active, has an even temperament, is seldom worried. He has no interest in clubs or organized activities. Seems to take an interest in his children. (In later years the father lost the balance and evenness of temperament here reported and became unemployed much of the time. He died in March, 1935, at the age of 41, "apparently accidentally drowned.")
