While looking through the Irish Catholic parish registers, I found this entry:
1835 Parish Register, Ferns, Wexford
Baptized November 10, 1835, Parish of Ferns, Diocese of Ferns, County Wexford, Ireland
Sponsors: M Fitzharris
Note in right column: Found on the roadside near big tree
You can see it for yourself here: Mary, baptism, Ferns, Wexford.
Was she adopted? Did she grow up? What did she turn out to be? Did she ever wonder who her biological parents were? Or did she even know?
And I wonder if the strangers on the road ever looked back and asked themselves what became of their baby girl.
