When you found Rose Ann's Baptism was there other info on the record. I have a copy of Simon and Mary's Death Records which has parents of Simon as Rose Ann Lynch and James Brannan. I have the Baptism Record for James and then I have the marriage record for his parents Simon and Margaret.
I was never sure whether Agnes was named Agnes or Ann as the 2 census records I have list Ann in one and Agness in the other. I would love to trade info with you on atlest Agness.
