You might have a valid case if Edgardo had decided to convert to Judaism as an adult. He did not ,so you can complain all you want,Edgardo made his choice freely,thus following God's will IMHO.
I wish you a Blessed evening!
No complaints, just observations mixed with sadness at the hard-heartedness of people who would use God's Will as a justification for taking a child from its parents JUST so that the child would not be raised as a Jew.
Poor Edgar Mortara!
Poor Momolo and Marianna Mortara!
