Kilrush (Kilkee)

Looking for info on Catherine RUSSELL (b. ca 1803) from Kilkee, Kilrush, Clare and her siblings John, Eomond/Eamon and Mary. There's thought to have been a Sinon/Senan name passed down through the family. 

Catherine RUSSELL married Thomas CURRY (possibly CURRIE, b. ca 1801, possibly Lisluinaghan, Kilfearagh) around 1820. Their children were James, John, Francis, Patrick (b. 17 March 1837 in Ireland, d. 7 December 1919 in Ontario, Canada), Mary Ann, Sinon/Senan and Michael. There may have been others. Catherine and Thomas are believed to have left Ireland in 1848 for Canada, leaving some of their older children behind. 

John RUSSELL may have had some connection to Col George WYNDHAM, 1st Baron Leconfield and may have emigrated to Canada with a group of Wyndham tenants from Clare. I have been unable to confirm this, although the information is purported to have come from correspondence between John and one or another of his siblings, most likely Eomond/Eamon. 

Any information would be deeply appreciated.
