update: just had a call back from ireland re checking the dragon oil shares - sadly already paid out 
anyway, I called them on 0333 300 1580 and asked them to look into it, left a few days and they called back to confirm that the shares had been paid out in 2015 and in Sept 2015 there was a share consolidation which reduced the number of shares by about 4 and was then paid out at £8/share. As this was done automatically this could be why still had some of the original dragon oil share certificates. So sadly, nothing outstanding
re Dragon Oil shares - I've just had an update from LinkGroup - Emirates National Oil Company (ENOC) successfully took over Dragon Oil plc in August 2015. Dragon Oil plc shareholders were entitled to receive a consideration payment of £8.00 per Dragon Oil plc share held. Dragon Oil plc delisted from the Dublin and London stock exchanges on 7 September 2015, with the last day of trading being 4 September 2015. --- So does this mean the shares were cashed in or they may still have some value?
