Was Richard EVER known as Richard of York?

Someone on Facebook is claiming the following:

"Richard was known as Richard of York until he was nine years old, when he was awarded the Dukedom of Gloucester (1461). Actually, all of the Duke of York's children were 'of York' until otherwise titled."

Is that true?

Hm. Well, it's possible. His sisters are known as Anne of York, Duchess of Exeter; Elizabeth of York, Duchess of Suffolk; and Margaret of York, Duchess of Burgundy. But the same doesn't seem to be true for their brothers, including Richard, all of whom are known by their titles once they've received them, and before that merely as the children of Richard, Duke of York. Certainly, it would have been confusing to refer to little Richard as Richard as Richard of York while his father was living, and equally confusing after he had become Richard of Gloucester.

I think that our Facebook friend is just speculating based on the women of the family of Edward of Lancaster. But EoL was also known as Edward of Winchester after his birthplace, so possibly the child Richard was known as Richard of Fotheringhay.

At any rate, I know of no documents to support this person's assertion.
