Joe Biden, a proud Catholic, also has a very Jewish family

As Joe Biden preps to become the nation’s second Catholic president, the president-elect also has deep Jewish roots within his extended family.

Biden, 77, who regularly attends church near his home in Wilmington, Delaware, has been vocal about his Catholic upbringing, but all of his children grew up to marry Jewish spouses, The Jewish Chronicle reports.

Hallie Olivere, the wife of Biden’s late son, Beau, became Joe Biden’s first Jewish daughter-in-law when the pair got hitched in 2002.

The president-elect knew Olivere’s mother, Joan, since childhood and once joked that as a child he would’ve liked to have married her.

“I was the Catholic kid,” Biden said, according to the report. “She was the Jewish girl. I still tried. I didn’t get anywhere.”

In 2015, Beau Biden died of brain cancer and Olivere later began dating his brother, Hunter, who had been separated from his wife, Kathleen.

Joe and Jill Biden, both of whom are Roman Catholics, blessed the coupling, saying they had their “full and complete support.”

Hallie and Hunter Biden went their separate ways last year, partly due to the incessant media attention their relationship got from the press. Hunter Biden then met a Jewish South African filmmaker named Melissa Cohen and the pair got married within 10 days at her Los Angeles residence, The Jewish Chronicle reported.

The younger Biden marked the union by getting a tattoo of the word “shalom” in Hebrew letters to match that of Cohen’s, according to the report.

Ashley Biden, the only child from Joe Biden’s second marriage to Jill, also has a Jewish spouse — an ear, nose and throat specialist at a Philadelphia hospital named Howard Krein.

The pair tied the knot in 2002 during a mixed-faith Catholic-Jewish ceremony and Biden even danced the hora at the reception, the Jewish Chronicle reported.

“I’m the only Irish Catholic you know who had his dream met because his daughter married a Jewish surgeon,” Biden reportedly said in 2016.

Biden’s third child with his first wife, Neilia Hunter Biden, was killed during a car crash with her 30-year-old mother in 1972. Naomi Christina Biden was just 13 months old at the time.

The couple’s two sons, Beau and Hunter, survived.
