I am certain there is a relationship here. My ex-husband's great grandmother was Maria Rose Sbrocchi from Roseto, Italy. She married a Falconi. The family story is that her mother was killed by lightning and she was brought to this country by her father and raised in an orphanage in Louisville, Ky.
I am aware that the grandparents used to go to Chicago for funerals. maria Rose's father (Phillip) was an Italian ambassador and went to Australia where he died at age 99.
