McCann Baptism Records

In my research on the immigrant generation of the McCanns, I've found what may be their Baptism Records.  Here is what I have found:

George McCann:

• Parents: George McCann & Margt Hughes
• Baptized on October 2nd, 1824
• Location: Tynon, Armagh, Ireland
• Roman Catholic
• Diocese: Armagh

Catherine McCann:

• Parents: George McCann & Mary Hughes
• Baptized on April 14th, 1831
• Location: Clonoe, Tyrone, Ireland
• Roman Catholic
• Diocese: Armagh

John McCann:

• Parents: George McCann & Mary Hughes
• Baptized on July 10th, 1834
• Location: Clonoe, Tyrone, Ireland
• Roman Catholic
• Diocese: Armagh

Jane McCann:

• Parents: Tool McCann & Mary M.
• Baptized on August 27th, 1836
• Location: Aghagallon, Antrim, Ireland
• Roman Catholic
• Diocese: Down & Conner

Mary Jane McCann:

• Parents: Jas McCann & Mary Hughes
• Baptized on May 13th, 1836
• Location: Armagh, Armagh, Ireland
• Roman Catholic
• Diocese: Armagh

I couldn't find anything for Elizabeth.  Given that I am not even sure that is her name, I'm not surprised.  All the records list their ages as zero, but I don't think this comes from the underlying document. I am highly suspicious of the record form Jane McCann.  Parents seem wrong and it is a ways away from the other ones.  I suspect the mother listed for George McCann may have been a transcription error for Mary and the father listed for Mary Jane McCann may have been George instead of Jas.  If these are correct records, the family moved quite a bit.  I wonder if this ties to the father's profession or something else.  Here is a map showing all the locations and how close they are to each other.
