Joe Biden's family history features inter-faith marriages and deep-rooted ties to England. Read on to discover the details.

Joseph Biden, the 46th President of the United States, is known for his Irish ancestry. His English and Catholic family heritage, however, has been largely overlooked. Until now.

The Catholic Heritage Archive has helped us unlock a hidden chapter in Joe Biden's family story. His Catholic connections stem from the Baltimore area and while he was raised in Pennsylvania, his family before him resided in Maryland for several generations.

Irish roots

Joe Biden is fiercely proud of his Irish-American heritage. Our friends at the Irish Family History Centre traced his earliest Irish ancestor to County Mayo on Ireland's west coast. His three-times great grandfather, Edward Blewitt came from the town of Ballina.

Both of Joe Biden's parents have Irish ancestry but it was his less well-known English family lineage that intrigued us most.

Joe Biden's English ancestry

Joseph Robinette Biden Jr. was born in 1942. His father, Joseph R. Biden, Sr., was born in 1915.

The Biden family line stretches back to William H. Biden, born in the late 1780s in Sussex, England. The exact location that William Biden hails from has been debated. Some sources indicate that he may have been born in Cambridgeshire, England, as his memorial page on FindAGrave suggests.

William is the first Biden known to immigrate to the United States, where he married Mary Elkins on February 13, 1822.

This is likely to be the entry for Joe Biden's ancestor, William, in the 1840 US Census. View the full record.

William Biden died in Maryland in 1849 and is buried at Loudon Park Cemetery in Baltimore. He appears in the US Census Mortality Schedule of 1850 with his surname spelled Byden. His entry indicates that he was a stonemason and died of dropsy after being ill for six days.

What is dropsy?

The Biden surname crops up repeatedly in Westbourne, Sussex. This is the most likely place of origin for the Biden family. However, there is a two-year discrepancy between the published birth year of William Henry Biden and the transcriptions available online. His parents, James and Ann Biden (née Silverlock), seem to have baptized all of their children several years after their birth, so this oddity appears to be a family tradition. James Biden and Ann Silverlock married at Westbourne on 16 May 1785.

Catholic connections

Joe Biden's grandparents, Joseph H. Biden and Mary E. Robinette married in the parish of St Edward, Baltimore, Maryland in November 1914. Their detailed marriage record features in Findmypast's exclusive Catholic collection from the Archdiocese of Baltimore.

As with most old Catholic records, notes were added in Latin. The note added in the margin of the Bidens' record reads;

"Obtenta dispensatione in dispari cultu"


"Sponso haud baptizato"

These little notes imply that Joseph Biden was not a practicing Catholic when he married Mary. We know that he needed the dispensation from the church because Mary’s baptism record is included in the register. So what religious denomination was the Biden family before Joseph’s marriage to Mary?

Joseph H. Biden was officially converted to Catholicism on February 18, 1917, at St. Martin’s parish in Baltimore. On the record, the priest noted that he was Methodist beforehand. This was a conditional baptism, because of his adult status and his previous denomination.

Clearly, Joseph's adopted religion stayed with him. When he died in 1941, he was buried in a Catholic cemetery. On his death register, his cause of death was noted as a cerebral hemorrhage. His obituary was printed in Frederick News Post on September 29, 1941.

Mary Robinette (Joe Biden’s grandmother) was the daughter of George and Mary (Hannafe) Robinette. George was listed as a locomotive engineer in the 1900 US Census, residing in Baltimore, and was born in Maryland. His wife, Mary was born in Ohio. They were married in West Virginia in 1884.
