Arlo vs Sonny

Arlo and Sonny over time

Arlo and Sonny appear together in 4 published lists, across 65 years of shared records. Neither was ahead in more lists than the other.

The order between them changed and held in 3 of those lists — a change in that published list, never a claim that one name displaced the other.

Arlo reached its own highest recorded position earlier in 4 of those lists, and Sonny 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.
