11.2.1796 at Lauderdale's O'Byrne / 3.3.1796 at Col Barry's Byrne / 7.11.1803 at H Rowan's O Byrne / 3.2.1804 again / 15.11.1804 again / 14.12.1808 call on Byrne / 24.12.1812 write to N Byrne. In Godwin's 1796 list for 1796
For the first two entries above perhaps Capt Gregory O'Byrne of 15th dragoons, Irish gamester 1779 (Walpole Correspondence 25:12) of 84 Pall Mall 1792 of 31 Clarges St 1799, in Paris 1802 and seized at English Customs for bringing back wine (see Morning Post 29.12.1801, 21.4.1802, 13.12.1802). Clearly N Byrne of 1812 was not him but was probably Nicholas Byrne will PCC 1833 of St Mary le Strand, and probably also the Nicholas Byrne printer of 18 Catherine St Strand 1794-5 and printer of the Morning Herald 1790 (Maxted) also proprietor of the Morning Post in 1810 (see Cobbett's Weekly Political Register 22.12.1810). Garret Byrne Dict Irish Biog c1762-c1832 was a United Irish leader in 1798 and according to Archibald Hamilton Rowan's autobiography was pardoned along with Edward Fitzgerald DNB c1770-c1807 in 1803 (confirmed by Nat Arch HO44/45/55 f154-5 28.3.1803). According to DIB he was allowed back to Ireland to settle his affairs but was in Hamburg at least 1799-1803 with Fitzgerald and lived his later days in England. He could possibly have been the Byrne of 1808. Archibald Hamilton Rowan also referred in his Autobiography to his old and valued friend O'Byrne helping him petition for a pardon in 1802. This must have been the O'Byrne at Rowan's in 1803-5 and was maybe Edmund O'Byrne son of the late James of Carlow who was admitted to the MiddleTemple in 1774.
