I would just like to point out that there is another possibility -- that NEITHER set of parents is correct! You can't base genealogy on "matching names."
How do you know that she was baptized at all?
Do you know where and when she died? Have you tried to find a death certificate (that might have her parents' names.)
Was she married? Have you tried to find marriage records? Those could also have parents' names.
Did she have any children? Their marriage and death records could include her maiden name.
You can't say this Agnes in this town "fits" so she's the right one....!
