Counties with Byrne in Ireland
Dublin was Byrne country: 35.8% of them (10,207 people) lived there in 1911. Next came Wicklow (3,712), Wexford (1,918), Carlow (1,793) and Kildare (1,455).
Byrne average age in 1911
The average Byrne in 1911 was 29.3 years old, 28.8 for men and 29.8 for women; almost exactly in line with the national averages of 29.6 for men and 30.5 for women. That low figure reflects just how many children there were in Edwardian Ireland, along with high infant mortality and the limits of public health at the time. For comparison, average life expectancy in Ireland today is around 83.
Byrne literacy in 1911
Of the Byrnes whose literacy was recorded, 78% could both read and write, 4% could read but not write, and 17.9% could do neither. The figures were much the same for men and women. Bear in mind these figures include young children; the census itself only counted people aged nine and over when calculating illiteracy, on the grounds that it was unfair to label a child illiterate before they'd had a chance to learn.
Byrne common first names
