Richard Quin

My grandmother Jane Quin was born in Cork in about 1865. She married in England in 1889 and according to her Marriage Certificate her father was Richard Quin, occupation "gentleman". I have searched for many hours and can find no information whatsoever about Jane or Father other than that she had an older sister Roseanna who was a nursemaid/governess in England and that her Mother's name was Nora. I have been unable to find any Irish records for any of the family and would greatly appreciate help
