Silly me, stupid mistake. My best guess is that Ann Stapleton was 'born on the sea' whilst sailing to North America / Canada - there is apparently a birth registration in Quebec in that name around 1795. Bannagher, Ireland, where her two daughters was born was the nearest(?) military establishment to Canada and there is a military record of a Michael Stapleton, 27th Regiment of Foot dated 25 Mar 1796. Then a death record of a Michael Stapleton aged 41 in Macclesfield in 1846 (obviously not the same person). Death reported by Mary Ann Stapleton - no relationship provided. Making sense of this information is what keeps me awake at night - LOL. Regards Carl
