Shading is the share of that state's recorded boys given this name, not the raw count — otherwise the map would just show which states are biggest. Unshaded states have no published records for this period. U.S. birth records suppress state-year counts below 5; state counts therefore don't add up to the national total. Every state links to its full rankings.

Geographically, Lachlan is somewhat regional — more concentrated than 57% of the names used widely enough to compare. See the most regional names
