Second registrar in the 1950s
Names where a second of the seven registrars first published a ranking between 1950 and 1959.
A fact about publication dates, not about a name travelling: it says when a second official dataset Namewise holds first ranked the name, which depends on when that registrar began publishing at all. Names only one registrar has ever ranked have no second record and appear in none of these bands.
