Too few records to say where it concentrates region by region — these are plain counts, not shares.

In Scotland’s registers today

Conlon was recorded 13 times in Scotland’s registers of births, marriages and deaths in 2025.

That made it the 1564th most common name in those registers, shared with others on the same count. In 1975, the first year of the series, the count was 14. Each birth counts the child’s surname, each marriage both partners’ and each death the surname of the person who died — a yearly count of registrations, not of the people who live in Scotland.
