Patrick P. Blewitt of Ballina Co. Mayo was a maternal great-great-grandfather of Joe Biden (46th President of the US). 

He came from a long family line of civil engineers and surveyors that left their mark on both Irish and US soil. His father Edward Blewett Sr. (1795-1871) worked on the Ordnance Survey of Ireland (a world-first). He then worked on the General Valuation (aka Griffith's Valuation – a popular census substitute). SOURCE

  • When Patrick was 16, he crossed the Atlantic working as a cabin boy. Upon his return, Ireland was in the grips of the great Famine and his father decided the whole family should emigrate.

Ballina's Blewett / Blewitt family were early Irish settlers of Lackawanna County PA, settling first at Carbondale.

For a few years, Patrick was employed at Scranton surveying lots with his father and travelled extensively in the Gulf (which brought him to South America and New Orleans)

  • In 1859, Edward F. Blewitt (Joe Biden's maternal great-grandfather) was born in New Orleans but the family returned to Scranton PA when he was 6 months old. 

  • For three years Patrick was surveyor of old Luzerne County, and also served as city engineer for Scranton. 

  • In addition, he had a large private business as a civil mining engineer.

  • In 1871 he was appointed mine inspector for the second anthracite district, extending from Carbondale to Wilkesbarre (from Provence to the Luzerne County line) and was reappointed every succeeding 5 years, having done "efficient work in the inspection fo the 46 mines there". 

Interestingly Scranton and Ballina today are twinned sister cities.


  • Edward F. Blewitt  (Patrick's son and Biden's great-grandfather) went on to become the first Irish Catholic to serve in the Pennsylvania General Assembly. 


Blewett /Bleuett (aka Bliúit/ Blaod / Bluet/ Bleuitt) is an Anglo-Norman Irish surname most numerous in Cork and Limerick.

In County Mayo, it is rare and centres around the neighbouring parishes of Kilfian and Ballysakeery (between Killala and Ballina):

  •  Edward Bleuett of 24a Ballymackeehola was recorded here in Griffith's Valuation. His bachelor namesake was the only Bleuitt still there in the 1901 Census of Ireland

  • Edmond aka Edmund Blewitt of 4a Seeaghanbaun was recorded in Griffith's Valuation. He married into a Preston farm here. (See Ellen Preston living at 4b). 

  • Hubert Bluet aka Bluit of 1 Colladussaun was recorded in Griffith's Valuation. His unmarried sister (Mary Bleuitt 1812-1903) and son's family were still present in the 1901 Census

  • Lots of info on Joe Biden's maternal Irish roots, but no information about his paternal connection to Ireland? What's up with that? My G.G. grandparents, (James O'Donnell & Margaret Fitzgerald) were from County Cork. The were married in 1844 at St. Barthlomew's Catholic Church in Kildorrery Co. Cork. James and Margaret had their first child baptised in 1845, a daughter who they named Bridget.

    James, Margaret, and Bridget fled Ireland, in 1848, during the "Great Hunger". They settled in Clairville, Ontario; Canada. Margaret gave birth to 8 more children in Clairville. In birth order they were named: Ellen, Thomas, John, Mary Ann, James(my G. Grandfather), David, William, and Michael.

    James and Margaret purchased 4 Lots in Clairville, in 1877. Margaret died in April of 1887, followed closely by James' death, in July of the same year.

    That's my Irish ancestral biography.
