Downton Abbey, Series Three (1920-1921)

Lady Edith Crawley:
Now that the funeral's over, we ought to think about the christening. Do know what you'd like her to be called?

Tom Branson:
I'd like to call her Sybil.

Matthew Crawley:
Of course.

Robert Crawley, Lord Grantham:
You don't think it might be a little painful?

Tom Branson:
Very painful at first, but I think it's right. I want to remember her mother whenever I look at her.

Lady Edith Crawley:
Of course you do. And she would want to be remembered. I'll go and see Mr. Travis this afternoon.

Tom Branson:
Why Mr. Travis?

Lady Edith Crawley:
To fix the date.

Tom Branson:
But Sybil will be Catholic.

Robert Crawley, Lord Grantham:
What?!

Tom Branson:
My daughter is Irish and she'll be Catholic like her father.
