This post explores genealogical collaboration between the author in Cincinnati and a DNA cousin in Brisbane, Australia. Together, they’re researching whether Ellen McAuliffe (Brooklyn, 1857) and Margaret McAuliffe (Australia, 1845) were sisters, both daughters of Florence McAuliffe and Ellen Healey from Listowel, County Kerry, Ireland. Using DNA matches across multiple platforms and family tree comparison, this international collaboration demonstrates why finding living relatives is the best part of genealogy.
