The medals are the Queen's South Africa Medal with 5 clasps and the King's SA Medal with 2, both from the Boer War. The third looks like the Long Service and Good Conduct Medal.
There's a service record on FindMyPast for one Patrick Flannery, born c.1863 in the East Indies (i.e. India), who served with the Royal Fusiliers from 1882 to 1907, including 3 years in the Boer War. He too received the QSA with 5 clasps (Cape Colony, Orange Free State, Transvaal, Tugela Heights, Relief of Ladysmith) and the KSA with both (1901, 1902), and the LSGC medal. His record gives his next of kin as a brother Edward in Toronto, a sister Julia in New Hampshire USA, and it states that he married Maud Eldridge in Hounslow on 19/10/1890. Is this your relative??
