Counties with Teahan in Ireland
The Teahans were heavily concentrated in Kerry, home to 96.7% of them (323 people). Next came Tipperary (6), Cork (4) and Offaly (1).

Teahan average age in 1911
The average Teahan in 1911 was 24.7 years old, 24.0 for men and 25.3 for women; noticeably 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.
Teahan literacy in 1911
Of the Teahans whose literacy was recorded, 62.5% could both read and write, 1.3% could read but not write, and 36% could do neither. Women came out slightly ahead, 64.2% reading and writing against 60.4% of men. 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.
