Laddie is an informal Scottish term of address for a young boy, derived from the Gaelic word 'lad'. It is often used endearingly to convey familiarity and friendliness. The name Laddie is also sometimes given as a first name in its own right, particularly in Scotland and other parts of the UK. It has no specific historical figures or notable people associated with it, but rather carries a sense of youthful spiritedness and warmth.
"The name Laddie saw its peak popularity between 1924 and 1928, with seven births each year during that period. However, it has not been particularly common overall, with only 92 total births recorded over the given years."
