My first known Wickliffe ancestor is Samuel Wickliffe born about 1827 in County Antrim, Ireland.
By 1851 he was in Quebec, Canada where he married Mary Tiunelly, also from County Antrim.

A search of the 1911 Irish census gives 10 entries for Wickliffe. They appear to be in 4 households.
One household with 3 Wickliffes is the household of a 37 year old John, wife Sarah and their daughter Alice. With them is living a niece with the last name Williamson who was born in Norway....
Another household is that of a John Wickliffe, indexed as 42, but I believe it reads 62, his wife Sarah Jane and their daughter Agnes Jane.
Another household is that of a Joseph Wickliffe, age 59, his wife Catherine and their niece Mary Wickliffe, age 14.
The last household is that of Sarah Jane Wickliffe, widow age 73, quite likely Sarah Jane Adams, the widow of Moses Wickliffe.
