Place & story
More residents and houses
Castlereagh townland’s population rose from 165 in 1911 to 212 in 1926. The later census records ninety-eight male and 114 female residents. Its forty-seven houses included forty-six inhabited dwellings and one empty house, compared with thirty-two houses in 1911. The return places the townland within Castlereagh electoral division and rural district and gives its area as 415 acres, two roods and five perches. The electoral division also included Cregagh and Lisnasharragh; its 618 inhabitants were therefore a different total from the townland’s 212. [2]
