When did the Imprescia's (and other family members) Immigrate?

The Impresica-Costa Family History document attempted to list out the immigration history of the Imprescia's and Costa's from Pietraperzia to Massachusetts.  Using documents available from passenger lists to Boston and New York I wanted to try to put together a timeline for arrivals in USA for our family.  From the "Family History" the timeline looked like this:

Filippo and Filippa (Siciliano) Imprescia left for America a short time after their wedding in Italy in 1908.  Salvatore and Vincenzo (Imprescia) Costa left for America in 1905 with their son Anthony.

What I have found:

1893

Although not an Imprescia, Giuseppe Carbone, age 44, father of Luigi Carbone (future husband of Anna Imprescia) left Lapio Italy on SS Weser which arrived in New York on 15 May 1893.  He was traveling with his brother-in-law Vito Costanza (married to his sister Maria Rosa Carbone).  Their final destination was Massachusetts.  Neither Giuseppe or Vito stayed in the United States and lived the remainder of their lives in Italy.  Giuseppe’s brother Antonio had immigrated as early as 1883 and is one of the earliest Italians to settle in Fitchburg.

1903

The first Imprescia arrival that I could track was Filippo Imprescia in 1903.  I cannot find the passenger list from 1903 with his name on it.  This was from his 2nd arrival in 1908, it lists whether passenger has ever been in United States before, he answered yes in 1903 in Boston.

    

1905

I could not find Salvatore Costa in passenger list but I could find Maria Vincenzo and Antonio (who was under 1 year old at the time) listed on the registry of the SS Romanic that travelled from Naples to Boston in 1905. 

So I assume Salvatore arrived sometime before or was on the passenger list and I could not locate him.  

Dominic Imprescia also travelled alone to the United States in 1905, leaving his wife Anna and daughter Concetta in Italy.  He departed Naples on April 26, 1905 and arrived in Boston May 8th, 1905 on the SS Canopic, it is listed on registry that he was joining his son Fillippo at the address 3 North Sq., Boston. It also noted that his son paid for his passage and he arrived with $2.00 in his pocket.

1906

One year and five months after Dominic Imprescia arrived in the United States, his wife Anna Viola and daughter Concetta boarded the SS Canopic on October 7th, 1906 and arrived in Boston on November 12th.

1907

Maurice Montesion, my wife's grandfather, came to New York from Lacedonia, Avellino when he was 18 aboard the Regina D'Italia.   He was listed as a shoemaker with $12 in his pocket. His final destination was with his uncle Michele Cardellicchio at 201 Water St. Boston.  His uncle had arrived earlier in 1905.

1908

Some time in before 1908, Filippo went back to Italy to get married.  On 23 January 1908 Filippo married Filippa Siciliano in Pietraperzia. Sixteen days after their wedding the couple then departed Italy on 8 February 1908 to New York on the SS Roma and arrived on 24 March 1908.

1912

Salvatore Siciliano (age 53), Filippa (Siciliano) Imprescia's father came to the United States with two of his sons Alisandro (age 19) and Giuseppe (age 16). The trip was paid by Filippo on the SS Canopic and it arrived 12 September 1912  in Boston. Salvatore and Giuseppe did not stay in the United States, but Alisandro did stay and in 1922 married Mary Cali and had six children: Samuel, Pamela, Jane, Leon and Joseph.

1913

Luigi Carbone, future husband of Anna (Imprescia) Carbone, came to the United States when he was 14 years old.  His father Giuseppe had already died in Italy in 1903.  He came with his mother Maria Gaetana Iovine (age 50) and two sisters Giovanna (age 25) and Carmella (age 22).  They were coming to stay with Giuseppe (Joseph) Carbone, Maria Gaetana's older son who immigrated some time around 1908 and lived on 22 Middle St, Fitchburg.

Giovanna married Michael Champa and Carmella married Vito Colello and both lived in Fitchburg.

The immigration from Italy was a family affair, as they earned money working in the United States they would send money back to pay for passage of relatives who would then live with them when they arrived until they could find jobs and get their own apartments and homes.
