The second season of Sloinne, a family history documentary series exploring common Irish surnames, has just finished airing – with all episodes from both seven-part seasons now available to watch online for free via the TG4 Player.
Two full seasons of the Irish surname genealogy docuseries Sloinne, totalling 14 episodes, are now available to watch on the TG4 Player anywhere in the world. Named after the Irish word for “surname”, this Irish-language documentary, complete with English subtitles, explores the origins and history of some of Ireland’s most common family names.
A D V E R T I S E M E N T
Each 50-minute episode follows a special guest, each one bearing a different surname, as they trace their lineage and uncover stories from their family’s past and that of the wider clan. They are helped along the way by historians and genealogists. The featured guests visit historical sites linked to their surnames, from humble ancestral homesteads to impressive castles associated with notable figures in Irish history. The format blends genealogy, history, folklore and archaeology.
Season two’s seven episodes, broadcast in May and June this year, focused on the surnames Fitzgerald (Mac Gearailt), O’Brien (Ó Briain), O’Neill (Ó Néill), Keane (Ó Catháin), Power (de Paor), Lynch (Ó Loingsigh) and Gallagher (Ó Gallachóir). The seven episodes of season one, which aired last year, explored the surnames O’Flaherty (Ó Flaithearta), Murphy (Ó Murchú), Kelly (Ó Ceallaigh), O’Sullivan (Ó Súilleabháin), O’Donnell (Ó Domhnaill), Joyce (Seoighe) and O’Connor (Ó Conchubhair).
