separated at birth: Mrs Bates of Aragon

I haven't had one of those "who IS that actress?" moments recently. Somehow, I have not watched the original 1999-2000 UK version of Queer As Folk, to say nothing of the US version or the later remakes. But Jacob Tierney mentioned it as a precedent at the GLAAD Media Awards where Heated Rivalry won the new series award. Anyhow, as I watched Queer As Folk, the face of the actress -- it was her eyes -- that played Marie Threepwood/Marie Jones (the sister of one of the protagonists) was so familiar. The name popped out from the credits because I remember that name -- Maria Doyle Kennedy -- from Downton Abbey and somewhere else. She also played Catherine of Aragon in The Tudors. She rather looks like the actress that played Miss Baxter in Downton Abbey. Her filmography in IMDb is extensive but Maria Doyle Kennedy has always got that penetrating look.
