I noticed your entry about Captain Monteith . I have just inherited my grandfather's papers and his account of his days in the Irish Volunteers and IRA. His name was Peter Reynolds , he owned a Motor Cycle repair shop and was used as a message courier and he records that "I had a message to deliver from the Countess Markievice to Captain Monteith ....... I left my house (164 North King Street)on a motor cycle at 2.30 (Infuriatingly he does not say what day, but it was in his entries for 1914) to meet the captain at Nelson's Pillar ( by the GPO in O'Connell St, or Sackville St as it was.)On the way my grandfather write that he had an accident and was taken to hospital but refused to stay as he had to meet Monteith, which he did, and delivered the message..
Hewrites of further meetings and of being present when police came to Monteith's house (after he had returned from USA) with an order for him to leave Dublin. Apparently Monteith was sent to Athboy some 42 miles from Dublin.
