In Scotland’s registers today

Muldoon was recorded 22 times in Scotland’s registers of births, marriages and deaths in 2025.

That made it the 1076th most common name in those registers, shared with others on the same count. In 1975, the first year of the series, the count was 28. 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.
