These odds and ends of Irish record notes may help you with your Condy search.
Irish Civil Marriage Record indexes:
William SOMERVILLE & Isabella CONDY Marriage Date: 11 February 1868 Ballyreagh Presbyterian Church Carnteel Parish, Dungannon Civil District, County Tyrone
John ARMSTRONG & Elizabeth CONDY Marriage Date: 13 November 1883 Drumquin Presbyterian Church Longfield Parish, Omagh Civil District, County Tyrone
Registers of Ballyreagh Presbyterian Church begin in 1843 and would very likely have more entries on Isabella Condy's family -- perhaps her birth and some of her siblings' births, and her parents' marriage (if 1843-1845). The same minister served Ballygawley, and that register might include your family as well.
Drumquin is a town in Longfield East parish, approx. 7 miles NW of Omagh. Drumquin Presbyterian Church registers begin in 1845.
Most Northern Ireland Presbyterian church registers are on microfilm at the Public Record Office of Northern Ireland in Belfast and can be researched. PRONI has several helpful databases on-line, including Freeholders lists, Will Calendars, and Ulster Covenant signers -- www.proni.gov.uk/
The 1841-1851 census abstracts for Old Age Pensions in Ireland include an Archibald Condy family in Drumnamalra, Longfield West, Co. Tyrone.
Cullentra (where Eleanor says her ancestor Alexander CONDY lived and farmed) is the name of townlands in Killeeshil parish and in Aghalurcher parish.
