When it comes to the Irish, Delaware County, and the Delaware County Historical Society, have a stake in Based on a 2013 Forbes story called “America’s Most Irish Towns,” Jed Kolko, Trulia’s Chief Economist, took a look at the places where most of Irish Americans live in the United States. And, lo and behold, among the top rankings came Crum Lynne at Number Six on the list with a purported 39.2 percent of its population claiming a connection to the Emerald Isle. Yet, that might cause a scuffle to arise with Havertown, Pa., if Wikipedia’s claims are to be believed in that that particular municipality likes to refer to itself as the “33rd county,” extending the boundaries of Ireland’s own 32 counties on the other side of the Atlantic. In conjunction with St. Patrick’s Day, the Delaware County Historical Society has celebrated by creating a correlated display, showcasing a sampling of books to be found in the stacks in the library. Among the offerings is a genealogy of Irish and Scotch-Irish written by Margaret Dickson Falley, dating to 1892, as well as Irish genealogies with an index to the towns, parishes and baronies of Ireland with a census of Ireland for 1851. There’s also Irish in America , the third volume of the memoirs of Albert D. MacDade that even includes a map. These books, and many more, are available at Delaware County Historical Society Museum, Library & Research Center. The museum is open to the public from 9 a.m. to 4 p.m. Wednesday and Friday; 1 to 6:30 p.m. Thursday; and 9 a.m. to 2 p.m. Saturday. The museum’s telephone number is 610-872-0502. Parking is free on the society lot behind the building or across the street in the municipal lot.
