What it means
Celtic root with two competing readings: 'harmony' (from a Brittonic alyn) or 'little rock' (Irish ailín). Alan Turing the cryptographer + Alan Rickman the actor anchor different generations.
Alan comes from a Celtic root with disputed meaning, candidates include 'harmony,' 'little rock,' 'noble,' or 'precious child.' The name arrived in England with the Bretons after the Norman Conquest in 1066. Alan Turing (1912-1954), the British mathematician who broke Enigma at Bletchley Park and founded computer science, is the deepest 20th-century anchor. Alan Rickman (1946-2016), the English actor of Die Hard, Sense and Sensibility, and Snape in Harry Potter, gives modern Hollywood weight. Alan Alda (M*A*S*H) covers the third generation. The English Alan peaked in the 1940s; it's been sliding since but is still in the US top 300. Common short: Al.
