Singer and actor Harry Connick Jr recently unearthed his Irish ancestry on the PBS documentary series “Find Your Roots”.

The star of “Will and Grace” discovered that his great fifth grandfather, David McCullough, was originally from a County Down village. McCullough was born in 1738 in the town of Rathfriland.

The County Down man went on to become a wealthy sea captain and “legal pirate” before he moved to Philadelphia. He had seven children and died at the age of 57.

Connick Jr. realized his roots by tracing his family tree through to McCullough’s daughter, Phebe.
When his Northern Irish roots were revealed Connick Jr said “That’s so cool!”

Martha Stewart, Robert Downey Jr, Barbara Walters and Kevin Bacon will also delve into their family’s past on the PBS show.

Here’s Harry Connick Jr. singing “And I love her”:
