Faith suffers from Spastic Diplegia Cerebal Palsy and a rare hearing condition called ANSD. She is unable to walk, crawl, stand or sit up unaided.
The Browne family have set up a GoFundMe page in a bid to raise €100,000 - the sum needed to help fund a life-saving operation in America.
Talking to Neil Prendeville on Cork's Red FM, mum Lisa said that they were ecstatic to receive such a incredible donation from the footballer.
"A friend of ours in Mallow messaged him and asked him if he’d send on a Republic of Ireland jersey to auction it off for Faith,” Lisa explained.
“He got back to us and he said James McClean was after donating €1,000 to Faith’s GoFundMe.
“As a family, we’d like to say thank you so much to James McClean for donating that money. It’s fantastic.”
So far, thanks to the huge number of incredibly generous donations, the family have raised a whopping €50K - that's half of their €100,000 target.
