I have looked up info for Arcangelo Giuseppe Menghini on familysearch.org as he was born and baptized on October 18, 1885 in San Floriano, Arsio, Brez, Trento, Italy. His parents were father: Simone Menghini and mother: Agata Niderjausner. per Italy, Trento, Diocesi di Trento, Catholic Church Records, 1548-1937. This area was known as Tirol, Austria. Later South Tirol and later became part of Northern Italy. There was info on ancestry.com for Francesca Floretta as she immigrated from Cloz, Austria and arrived in New York on February 2, 1909 on the Ship Name: St. Louis Age 16 Final Destination Rock Springs, Wyoming!
My great grandfather was named Giuseppe Menghini and he was born in 1845 in the same area. He later came to Rock Springs, WY and was said to have died there on April 7, 1889. I have been unable to find a death record or grave for him. My great grandfather late immigrated to the U.S. through South Dakota.
You can also find your great grandparents info on findagrave.com and type their names in. There is a bio on both of them.
I hope this info is helpful in your search.
