Peadar Toner Mac Fhionnlaoich, Irish language writer during the Gaelic revival known as Cú Uladh (The Hound of Ulster), is born in Allt an Iarainn, County Donegal on October 5, 1857. He writes stories based on Irish folklore, some of the first Irish language plays, and regularly writes articles in most of the Irish language newspapers such as An Claidheamh Soluis.
Mac Fhionnlaoich is the son of Micheal McGinley and Susan Toner. He attends school locally until he is seventeen. He then attends Blackrock College in Dublin for two years. Upon leaving school he enters into the British Civil Service becoming an Inland Revenue Officer. In 1895 he marries Elizabeth Woods (Irish: Sibhéal Ní Uadhaigh) and they have twelve children. He speaks Irish from an early age and keeps an interest in the language throughout his life, first publishing an Irish language short story and poem in The Donegal Christmas Annual 1883. It is not until 1895 while living in Belfast that he becomes involved in the Gaelic Movement.
It is in Mac Fhionnlaoich’s Belfast home that the first meeting of the Ulster branch of the Conradh na Gaeilge takes place in 1895. From this point on he becomes very involved in Conradh na Gaeilge becoming the organisations president on several occasions.
Mac Fhionnlaoich dies at the age of 84 on July 1, 1942 in Dublin. He is buried in Glasnevin Cemetery, Dublin.
