Lenihan in 1911 Ireland
The 1911 Census recorded 918 people named Lenihan in Ireland; roughly one in every 4,800 people carried the name. The name was split fairly evenly between men and women: 470 men and 447 women. (A small number, 1, had no sex recorded.)
Counties with Lenihan in Ireland
Cork had the largest share of Lenihans, 22.2% (204 people). Next came Limerick (194), Kerry (179), Waterford (79) and Clare (69).

Lenihan average age in 1911
The average Lenihan in 1911 was 27.2 years old, 26.6 for men and 27.8 for women; a touch younger than 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.
Lenihan literacy in 1911
Of the Lenihans whose literacy was recorded, 76.5% could both read and write, 4.1% could read but not write, and 19.4% 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.
