Every other year, usually in the Fall, Clan Ewing hosts a gathering of its members at some location in the U.S. These gatherings' locations are chosen to provide access to local sites of high interest to Ewing genealogists, for example, graveyards with many Ewing burials, libraries with extensive Ewing research resources, towns founded with the leadership or extensive help of Ewings, etc. The gatherings provide the opportunity to interact, face-to-face, with cousins and other Ewing genealogists. They also provide access to the Archives maintained by Clan Ewing at The Historical Society of Cecil County, Elkton, Maryland, as well as other research materials brought to the gathering by attendees. In addition, they provide seminars and workshops on topics of current interest - for example, the use of Y-DNA testing to confirm the conclusions of traditional genealogical research - and presentations about the status of Clan Ewing activities - for example, the Ewing Genealogy Documentation (EGD) Project.

The most recent gathering - the ninth - was held in Fort Wayne, Indiana, September 21-24, 2006. The next, tenth, gathering will be held September 18-21, 2008, in Winchester, Frederick County, Virginia. This location in the Shenandoah Valley was settled by many Ewings who first immigrated to the upper Chesapeake Bay area and then migrated south and west when the Shenandoah Valley land was opened for settlement between the end of the French and Indian War (1762) and the beginning of the Revolution War (1776). The eleventh gathering will be held in the Pittsburgh, Pennsylvania, area in Fall 2010. This area was another target for migration from the upper Chesapeake Bay area in the 1762-1776 period, not only for Ewings who settled the Pittsburgh area but also for Ewings who used their cousins as "bridges" to settlement further west.
