Is Allie Byrne the daughter of Michael Byrne?

I'd always thought she was, and IMDB records it in the Family Relationship section. But his obituary https://www.theguardian.com/stage/2026/jun/30/michael-byrne-obituary does not list her as a daughter. I've also found https://en.wikipedia.org/wiki/Allie_Esiri "Esiri's acting name was Allie Byrne, though she was born Allison Burns."

So it looks as if this information is wrong. Unless anyone knows differently, I'll remove the family link and the trivia entry for Michael Byrne.
