1. Brigid of Kildare (451 - 525)

With an HPI of 75.96, Brigid of Kildare is the most famous Irish Religious Figure.  Her biography has been translated into 34 different languages on wikipedia.

Saint Brigid of Kildare or Saint Brigid of Ireland (Irish: Naomh Bríd; Classical Irish: Brighid; Latin: Brigida; c. 451 – c. 525) is the patroness saint (or 'mother saint') of Ireland, and one of its three national saints along with Patrick and Columba. According to medieval Irish hagiographies, she was an abbess who founded the important abbey of Kildare (Cill Dara), as well as several other convents of nuns. There are few documented historical facts about her, and her hagiographies are mainly anecdotes and miracle tales, some of which are rooted in pagan folklore. They say Brigid was the daughter of an Irish clan chief and an enslaved Christian woman, and was fostered in a druid's household before becoming a consecrated virgin. She is patroness of many things, including poetry, learning, healing, protection, blacksmithing, livestock, and dairy production. In her honour, a perpetual fire was kept burning at Kildare for centuries. Some historians suggest that Brigid is a Christianisation of the Celtic goddess Brigid. The saint's feast day is 1 February, and traditionally it involves weaving Brigid's crosses and many other folk customs. It was originally a pre-Christian festival called Imbolc, marking the beginning of spring. Since 2023, it has been a public holiday in the Republic of Ireland. This feast day is shared by Dar Lugdach, who tradition says was her student, close companion, and successor.

Columbanus taught an Irish monastic rule and penitential practices for those repenting of sins, which emphasised private confession to a priest, followed by penances imposed by the priest in reparation for the sins. Columbanus is one of the earliest identifiable Hiberno-Latin writers.

4. Columba (521 - 597)

With an HPI of 67.83, Columba is the 4th most famous Irish Religious Figure.  His biography has been translated into 53 different languages.

Columba () or Colmcille (7 December 521 – 9 June 597 AD) was an Irish abbot and missionary evangelist credited with spreading Christianity in what is today Scotland at the start of the Hiberno-Scottish mission. He founded the important abbey on Iona, which became a dominant religious and political institution in the region for centuries. He is the patron saint of Derry. He was highly regarded by both the Gaels of Dál Riata and the Picts, and is remembered today as a Catholic saint and one of the Twelve Apostles of Ireland. Columba studied under some of Ireland's most prominent church figures and founded several monasteries in the country. Around 563 AD he and his twelve companions crossed to Dunaverty near Southend, Argyll, in Kintyre before settling in Iona in Scotland, then part of the Ulster kingdom of Dál Riata, where they founded a new abbey as a base for spreading Celtic Christianity among the pagan Northern Pictish kingdoms. He remained active in Irish politics, though he spent most of the remainder of his life in Scotland. Three surviving early-medieval Latin hymns are attributed to him.

5. Mary Jane Kelly (1863 - 1888)

With an HPI of 64.73, Mary Jane Kelly is the 5th most famous Irish Religious Figure.  Her biography has been translated into 24 different languages.

Mary Jane Kelly (c. 1863 – 9 November 1888), also known as Marie Jeanette Kelly, Fair Emma, Ginger, Dark Mary and Black Mary, is widely believed by scholars to have been the final victim of the notorious unidentified serial killer Jack the Ripper, who murdered at least five women in the Whitechapel and Spitalfields districts of London from late August to early November 1888. At the time of her death, Kelly was approximately 25 years old, working as a prostitute and living in relative poverty. Unlike the other four canonical Ripper victims—each of whom had been murdered outdoors and whose mutilations could have been committed within minutes—Kelly was murdered within the sparsely furnished single room she rented at 13 Miller's Court, affording her murderer an extensive period of time to eviscerate and mutilate her body. Kelly's body was by far the most extensively mutilated of the canonical victims, with her mutilations taking her murderer approximately two hours to perform.

8. Dymphna (700 - 700)

With an HPI of 63.80, Dymphna is the 8th most famous Irish Religious Figure.  Her biography has been translated into 23 different languages.

Dymphna (also Dimpna, Dymfna, Dimfna, Dympna and Dympha, Irish also Damhnait or Davnet) is a Christian saint honoured in Catholic and Eastern Orthodox traditions. According to tradition, she lived in the 7th century and was martyred by her father. The story of Dymphna was first recorded in the 13th century by a canon of the Church of Aubert of Avranches at Cambrai, France. It was commissioned by Guiard of Laon, the Bishop of Cambrai (1238–1248). According to oral tradition, the bones of St. Dymphna were discovered and produced a miracle: a dead man was revived after being beaten with her bones. This event was regarded as proof of the miraculous power of her relics. This story could go back to a variation of the Bible story from 2 Kings 13:21, in which a dead man was brought back to life through contact with the bones of the Prophet Elisha. The author of the 13th century account expressly stated that his work was based upon a long-standing oral tradition as well as a persuasive history of miraculous healings of the mentally ill.
