Hall and McAuley Family

Hi, My name is Ruth Williamson Hall. I have traced some of the Hall family to Dublin and Antrim County. Alexander Hall and Catherine McAuley were married in 1848 in Murray Township, Nothumberland County, Canada. However there first child, Elizabeth was  before the marriage in Canada. I have her baptism certificate from St. Patrick's Catholic Church, Loughguile Parish, Cluntfinan Townland, Antrim County, Ireland stating was baptisedas  illegitimate  on13 Sep 1845.

Found in the 1851 census for Murry Township, Northumberland County, Ontario, Canada.
"HALL, James, laborer b. Ireland 46, Jane b. Ireland 50
Canner, Eliza, b. Ireland 8
HALL, Alex, b. Ireland 29, Catherine b. Ireland 25, Ann 4, Joseph 2
Consession 1 Lot 12"
According to this census Alex was born in 1822 and according to years old on death certificate he was born in 1817.
James probably was an  older brother of Alex. They lived together.
