Carmen de Areco

Carmen de Areco was the most Irish district of Buenos Aires province in 1869. The census counted 433 Irish-born residents there, 8.46 per cent of the Irish in the province, according to the SILAS reading of Eduardo Coghlan's genealogy; by 1895 the figure was 287. Coghlan's records also list 98 Irish deaths in the partido. An 1863 list of foreign residents at the Fortín de Areco names 43 people, mostly Irish, the Irish Argentine Historical Society reported in 2004.

The IAHS page records the traces that remained about 2004. Estancias included Maguire's San Patricio and Michael Allen's Killallen. Allen, born about 1824 and died in 1893, built a chapel there dedicated to St Mel. The parish church has a memorial to an Irish chaplain of the 1860s, whose name the sources give differently, and stained glass given by Irish-Argentine women. The cemetery has Irish vaults, among them Furey, O'Donnell, Mullen, Murray and Gardiner. Streets are named after Juan Bautista Dowling, Miguel Antonio Duffy and Patrick Dowlin. Nally's 1992 survey lists Carmen de Areco among the places where churches were built for the Irish.

In 1868 Thomas Maguire gave land to the Irish chaplain for what became the Passionist monastery of San Pablo, which lies on Route 51 between Carmen de Areco and Capitán Sarmiento. The historians Korol and Sabato drew Carmen de Areco in their sample of the most Irish partidos, and Cruset writes that Irish surnames, churches, schools and cemeteries remain visible in them.
