Frank Loto of Manchester CT

I am researching the Loto Family starting from 1878 in Sicily, Italy. Our Ancestors Mario and Maria Loto came to the United States in 1906 from Allesandara della Rocca, Sicily, Italy. I don't know if our grandfather had any brothers who went to other countries, then their children came to the United States. There are other Loto families in the United States that came from Mexico etc, but we do not seem to be related to these other Loto's.

Maria Loto had three sisters who came to the United States.

Mario and Maria Loto had two girls Angela, born on June 2, 1906 and Alfonsina (Frances), born on November 13, 1908, and two boys Joseph, born on June 5 1910, and Frank born, on May 3, 1914. The family setteled in Tampa, Hillsborough county, Florida on November 10, 1906. They had resided continuously in the United States since October 28, 1906.

I am trying to find out if my grandfather had any brothers and if any of the Loto's from other countries are related, and how.

Any information would be appreciated.
