Sesto OR Fragola Family Names

Maternal grandparents emigrated to NY/NJ in approx 1915.
No Ellis Island records.
Guglielmo Sesto was an orphan.
Margherita Fragola was raised by an aunt. May have had a sister. My mother says there were from Ciminna, Sicily. but I cannot seem to verify that.
Mother and uncles NEVER spoke about the ancestry.
