Soghain

The 17th-century scholar Dubhaltach Mac Fhirbhisigh identified them as part of a larger group called the Cruithin.

A poem recorded in The Book of Uí Maine, Cruas Connacht clanna Sogain, lists the kingdom's boundaries, which can be found to tie in with the above locations: From Áth an Ibar west To Glais Uair Arnaigh Was the extent of Soghan That sword-guarded land.

From Béal na Róbe in Máenmagh To the clear, soft-reeded Simin Was the breath of the plain Which bore no ignominy.

Their successors include Naomhéid, Cuana of Kilcoonagh, Dubhán, Felig, Íbar, Íomar of the Sogain, Laisren of Clonkeenkerrill, Maol Chosna, Modiúit, Menott, Molua of Kilmoluagh.

Descendants of the Soghain are still found in great numbers in County Galway, bearing names such as Ó Mainnín, Mannion, Manning, Ward / Mac an Bhaird, Gill / Gillane, Scarry, Dugan / Duggan, Megan / McGann, Martin, and Cassain.
