Lattie is an uncommon yet charming given name of Scottish origin. It's derived from the Scottish surname 'MacLachlan', which means 'son of Lachlan'. The name Lachlan itself means 'follower' in Gaelic. Lattie is often used as a nickname or diminutive for longer names like Lachlan, but it can also stand alone as a unique choice.
The name Lattie experienced varied popularity over time, peaking in the early 20th century with a high of 20 births in 1919. However, it appears to have been less common towards the mid and late 20th century, with most years recording only 5 births or fewer after 1947.
