About the name Lachlan
The origin of Lachlan is debated, and we couldn't confirm its meaning from a sourced etymology. A commonly cited theory links it to Scottish roots, with the meaning âFrom the land of lakesâ. Treat that as a theory, not a settled fact.
Why we say this: we only state a meaning as fact when a sourced etymology (Wiktionary, with its references) supports it. For Lachlan we didn't find one we were confident in, so we show the popular explanation as a theory.
