Jac and Rian over time
Jac and Rian appear together in 1 published list, across 29 years of shared records. Jac held the stronger position in more years in 1 of them, Rian in 0.
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.
Jac reached its own highest recorded position earlier in 1 of those lists, and Rian 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.

| Record type | Official statistical record (evidence-only) | Editorially researched profile |
| Gender usage | male | male |
| Meaning | Not yet recorded | Traced to the Irish surname lineage behind Ryan (descendant of Riaghan/Rian) rather than a standalone root word. A popular claim that it means 'little king' is a folk etymology found on baby-name websites, not a scholarly derivation — the true root of the underlying Old Irish name is unclear. |
