The main cemeteries used for those killed in the Rising were Glasnevin, Deansgrange and Mount Jerome. He would only have been buried in Mount Gerome if he was protestant. He does not appear in the search on the Glasnevin website. Deansgrange and Mount Jerome do not have search facilities on their websites so you would have to contact the cemetery. He may have been buried in Grangegorman but only if he had a strong military connection.
It is unlikely he was buried unidentified. In order for a burial to take place a certificate had to be obtained from the military, it had to be proved that the dead person was who it was claimed they were. Coffins were opened and searched as they entered the cemetery and only one person was allowed to accompany the coffin to the grave site.
It is also very unlikely he is buried anywhere other than Dublin, because of the large number of bodies there was a fear of diseases spreading and burials took place as soon as possible after identification. It is also unlikely he was buried in Dublin and then re-buried somewhere else at a later date, there was a government department called the Sanitation department from whom permission had to be granted before a re-burial could take place, as far as I know only one re-burial took place and that was one of the Rebels Thomas Allen who was buried in Glasnevin and then re-buried in Longwood Moyvally County Meath in 1917.
