How Did the Rumor Start?

The rumor that Ned Dennehy and Brian Dennehy are related may have started because of their common surname and Irish heritage. According to, the name Dennehy is derived from the Gaelic name Ó Duineachaidh, which means “descendant of Duineachadh”, a personal name composed of the elements duine (man) and each (horse). The name is mainly found in County Cork, where it is very numerous

However, having the same surname does not necessarily mean having the same family tree. There are many people with the same or similar names who are not related at all. For example, Tom Cruise and Penelope Cruz are not related despite sharing a surname that sounds identical.

Moreover, both Ned Dennehy and Brian Dennehy have denied any familial connection between them. In an interview with Married Biography, Ned said: “Ned is not related to Brian Dennehy, the famous American actor best known for his roles in movies “Presumed Innocent” in 1990, “Romeo + Juliet” in 1996 and “Death of a Salesman” in 2000.” 

Similarly, Brian once joked about being mistaken for Ned’s father: “I’m always getting asked if I’m Ned’s dad – I’m not! I’m his uncle!”


Ned Dennehy and Brian Dennehy are two talented actors who share a surname and an Irish background but are not related by blood or marriage. They have both clarified this fact in interviews and have expressed admiration for each other’s work.
