 In the 17th century, John Colgan produced another Latin "Life" (the "Vita seu supplementum"), for which he drew on three Irish "Lives".Féchín is said to have been born in Bile, probably Billa in what is now the parish of Ballysadare (Kilvarnet), (Co. Sligo).The medieval "Lives" call his mother Lassair, identified in the Irish text (first part) as a member of a royal Munster line.
