Left-handedness
The Kerrs have typically been associated with left-handedness; some of their buildings, such as Ferniehirst Castle, have been explicitly designed with this in mind. There is an anecdotal link between the Kerrs and left-handedness, although it is unclear whether or not present-day individuals with the surname of Kerr have a higher incidence of left-handedness than the general population. An article appearing in the BMJ circa 1972 confirmed that about 30% of those with the surname Kerr were left-handed as opposed to a background 10% of the population. However, a 1993 study found no statistically significant increase in left-handedness among people with the family name Kerr or Carr.
