Although we haven’t found any trace of John F. Armstrong (1845-1893) before he left Ireland in 1865, we have located his father’s leased farmlands in County Sligo in Griffith’s Valuation.

Ireland is divided into four ancient provinces. On this map: 1) Ulster is light brown and dark brown, 2) Leinster is gray, 3) Munster is blue, and 4) Connacht (Connaught) is purple.

Looking at a map, it’s easy to see that Ireland is smaller than Great Britain. Comparing populations, though, takes a little more work.
