I just saw your message - I am related to Corkerys and Sheehans who immigrated from Ireland via Wales to Canton MA, arriving in the 1870s. Margaret Corkery Canniff (b 1840 Ireland, d 1911 Canton) was my ggg grandmother (she married James E Canniff in Ireland). Margaret's parents were Jeremiah Corkery (b abt 1819 Ireland, d 1887 Canton) and Catherine Sheehan (b abt 1812 Ireland, d 1896 Canton). Margaret's grandparents were Jeremiah and Mary Corkery, and Timothy and Mary Sheehan, all born in Ireland (I have no further info on these grandparents).
As far as I can tell, Margaret had at least 3 siblings: John F Corkery (b 1844 Ireland, d 1908 Canton), Anna Corkery (b 1856 Ireland, d ?), and Hanora "Nora(h)" M Corkery Mahoney (b 1859 Ireland, d 1884 Canton). Jeremiah and Catherine (Sheehan) appear on the 1871 Census of Wales (as "Corkey"), in Swansea, with their daughters Anna and "Norah" (sic), as does their married daughter Margaret (Corkery) Canniff, her husband James Canniff and their 5 oldest children (2 born in Ireland, 3 in Wales). Seems they went from Ireland to Wales for the men to find work in the steel mills, then left for the US when jobs dried up in Swansea (according to folks familiar with the history of immigration from Ireland to Wales and US). Son John left Wales for the US in the mid-1860s and lost touch with his family, but they appear to have been reunited again in Canton in the 1870s after the rest of the family arrived (around 1873), and placed newspaper ads saying they were looking for him. All the Corkerys and Canniffs (except Anna, who disappears from the records) are listed on the US Census of 1880, living in Canton.
I have copies of most of the Welsh & American birth, marriage and death certificates for these Corkerys and their decendents, but I have hit a wall in tracing either them or the Canniffs back to their place of origin in Ireland. I suspect they were all from Cork, but don't have any proof (yet).
Unfortunately, despite all of this, I don't seem to have your Hanora on my tree, but perhaps she was a cousin, or the details have gotten mixed up somewhere along the line. Let me know if you'd like more info/details - my family tree is also available on Ancestry.com. I also recently looked to see if there were any Corkerys left in Canton, and there are quite a few listed in the white pages - not sure if any are related to me. One, Luz M Corkery, has her job listed as "Corkery Genealogical, Treasurer." I haven't written to her yet or otherwise tried to track down this group, but plan to!!
Hope this helps, and that I'll hear back from you soon!
