A Munster name, counted off the birth index
In 1890 the Registrar-General of Ireland counted every surname on the country's birth index. Ryan appeared 715 times, with Tipperary recording by far the largest share of them.
Munster alone accounted for 473 of those births. Ulster accounted for thirteen. The name was Irish in a specific and local way, clustered in the south.
