Meaning and history
From an English surname meaning “son of Neil,” Nélson was originally given in honor of the British admiral Horatio Nelson (1758–1805), whose best-known victory was the Battle of Trafalgar, where he destroyed a combined French and Spanish fleet but was killed. Another notable bearer was the South African statesman Nelson Mandela (1918–2013), who was born Rolihlahla and received the English name Nelson from a teacher as a child.
Nelson moved from #778 to #825 for boys between 2024 and 2025. Its highest annual birth count came in 1959, with 1,084 births.
