I have done a bit of research and while I don't have any conclusive evidence that the relation exist there is fairly convincing evidence that there is a close relationship.
The Bridget kelly or O'kelly was born in Drumcomoge Emily Tipperary around 1861 she married William O'Brien from Mitchelstown Co. Cork, Bridget was married on 13/03/1890 and the witness were William Noonan & Margaret Galvin.
Bridgets mother was winifred Crowe born around 1815 (no record of her Birth exist) she is buried in Emly in the Kelly Grave Emly Tipperary after her death on 27th August 1875, her husband was John and his parents were Patrick Kelly and mary Moragan (all mentioned on the Headstone).
If winifred is one of the Crows from Ballyphilip kilteely then her father would be John Crowe and she had a brother John Crowe born around 1816 who married Johanna Dillion. He had seven children with one of the daughters called Winifred born in Kilteely 1854, so most likely this was a family name.
Johns oldest son was Thomas DOB 1853 who married Bridget Moloney and their eldest son was called Michael F Crowe (this is the GAA man). Bridget Kelly was a first couse to Thomas DOB 1853 or a first cousin once removed to michael F.
One other thing that appears to link the family is at the wedding of James Crowe (Michael F's brother) to Mary Heelan from Elton Knocklong in April 1894 the witness on the Crow side of the house was a John Kelly I expect he was one of Winifred's children however I am not able to trace him, I have some information on Winifred's three children, Patrick who stayed in the Home place and married Margaret English, Johanna who never married and Bridget who married O'Brien.
I hope this is helpful in making the link, if you have any further info I would welcome it, I am from Kilteely just over the Boarder from Emly and now live in caherline.
