Lachlan vs Luke
Lachlan and Lukecompared on official birth-registration statistics and Namewise's recorded data. This page states what each name's record shows — it never picks a winner or scores one name against the other.

Lachlan and Luke appear together in 5 published lists, across 131 years of shared records. Luke held the stronger position in more years in 3 of them, Lachlan in 2.
The order between them changed and held in one of those lists — a change in that published list, never a claim that one name displaced the other.
Luke reached its own highest recorded position earlier in 5 of those lists, and Lachlan in none. Each position is a place inside its own list, so this compares when they peaked and never how high.
Counted list by list. Two names in the same published list are measured on the same scale in the same year, so those comparisons are real — but positions from different lists are not, so nothing here is combined into an overall standing.

Two names moving past each other in a ranking is a fact about the ranking. Namewise does not claim one name displaced the other, that families chose between them, or that either influenced the other — none of that is in this data.

| Meaning | Traditionally understood as 'Viking' or 'Scandinavian' via its root name — someone associated with the land of the Norsemen. A secondary reading of that root gives 'land of the lakes'. | From Latin Lucas, from Greek Loukas — probably 'from Lucania' (a region of southern Italy), or possibly connected to Lucius. Luke was a physician who accompanied Paul and is traditionally credited as author of the third Gospel and Acts. |
