"CRUMLIN, or CROMLIN, a parish, in the barony of NEWCASTLE county of DUBLIN, and province of LEINSTER, 2 3/4 miles (S. W.) from the post-office, Dublin, containing 958 inhabitants, of which number, 544 are in the village, which consists of 115 houses."

"Alderman Michael Flanagan, bapt 29th Sept 1833,
hugely successful market gardener, starting with very little he built up business supplying the expanding Dublin city, eventually owned farming land all over SW Co.Dublin (Crumlin, Drimnagh, Rialto, Dolphin's Barn, Walkinstown, Greenhills, Tallaght, Kilmainham, Rathfarnham), most of which is now built-up suburbs today,"
"they say that all of Crumlin was under cabbage"

"Attempts to plan Dublin's development in the early twentieth century were based on British models, with new blocks of flats in the city center and new houses on the periphery (Marino, Glasnevin, and Crumlin) for poorer families (NESC 1981:66)."

"Housing became a main focus of the work of the Council and suburbs expanded in the 1930s to include Drumcondra, Crumlin, and Cabra, with later post-war developments in Ballyfermot and Ballymun."

Answer 2

There is this "story" that the bloke who designed the big huge housing scheme (all the roads that are named after monasteries - monasterboice, cashel, stanaway, derry, clogher etc) designed it in the shape of a celtic cross...and then he killed himself apparently, I heard that years ago of my gran, but dunno if its true.
