I found that the Waughs in my family living in Edinburgh c. 1840's came from Co Leitrim - from a Patrick Waugh and Honor McHugh, born about 1765/1770 ( 3 x great grandparents). Ther son James Waugh was a flesher who died in 1858. The Hoeys, also in Edinburgh were Costermongers living at Blackfriars Wynd, Edinburgh according to the 1851 census - but have had no luck tracing them back to their Irish county of birth. Some became shoe and bootmakers.
On the Glasgow side, we have the Fallen family - first noted as parents Dennis and Bridget Fallen, parents of John Owen Fallen who married a Sarah Gallacher, daughter of James Gallacher and Hellen Hoy at Alexandria, Bonhill, Dumbartonshire. Not had any luck finding where the Gallacher or Fallen family came from in Ireland.
