hi,
In Griffiths Valuation 1862 there is only one Thomas PHAIR recorded...
He is farming 9 acres of land at Cornashee Townland...
Tenant
Family Name 1 PHAIR
Forename 1 THOMAS
County FERMANAGH
Barony MAGHERASTEPHANA
Union LISNASKEA
Parish AGHALURCHER
Townland CORNASHEE
This looks like descendants of the family in 1901...

It doesn't look like they had any children ??
By 1911 the family are gone...

fyi
There would be no official records of Births, Marriages, Deaths before 1846 in Ireland.
There may be church records, but you would need to contact the Church in the Parish they were married.
I think this looks like your ancestor arriving in Canada in 1871...
Name: Robert Phair
Birth Year: abt 1825
Arrival Year: 1871
Arrival Place: Ontario, Canada
Age: 46
Source Publication Code: 1823.5
Primary Immigrant: Phair, Robert
Annotation: Date and place of census. Census films are available from the National Archives of Canada. Place of birth, religion, ethnicity, occupation, district, subdistrict, division, and page of original record are also provided.
Also arriving at the same time are...
Name: Edward Phair
Birth: abt 1826
Arrival: 1871 - Ontario, Canada
Name: James Phair
Birth: abt 1823
Arrival: 1871 - Ontario, Canada
Name: William Phair
Birth: abt 1827
Arrival: 1871 - Ontario, Canada
Name: Thomas Phair

Thats all I have I am afraid.
