Coleman

My grandmother had four siblings that died as todlers and I am trying to find out where they are buried. They were born in Omoores Forest, Co. Loais and the details I have are William Coleman born 11.2.1873 died 1874. Margaret born 26.7.1874 died 1876. Joseph born 21.6.1879 died 28.3.1881. Patrick born 22.5.1881 died 9.2.1883. any advice on likely cemeteries to try would be gratefully received.
