Shea vs Tamsyn
Shea and Tamsyncompared 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.
Head to head
Ranks are only compared within one published list and one year. Two ranks from different years, from a boys' and a girls' list, or from different registrars are not comparable, so they are not placed side by side.
England and Wales · Girls
In 2024, Shea was ranked #3015 and Tamsyn #5891 among girls in England and Wales.
Shea and Tamsyn over time
Shea and Tamsyn appear together in 1 published list, across 23 years of shared records. Tamsyn held the stronger position in more years in 1 of them, Shea 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.
Tamsyn reached its own highest recorded position earlier in 1 of those lists, and Shea 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.
