There is also another Francesco Paulo Nicola Martelli. I think this may be him. I do know that he had a son name Nicola. This Nicola was born about 1879. I figure the marriage was about 1872-1878.
If this is the correct one then the parents could possibly be Cesare and Maria Pasquini.

Thank you for the information.
I believe that Francisco's wife's name was Laura. I don't know the last name.

I am trying to trace back ancestors of Francesco Paulo Martelli b 1852 and also Antonio D'Amelio b 1856.
Would anyone be able to help me?
thank you
