Margaret appears to have been born in the US. I found her listed with George in the census of 1920.She was 31 and listed as born in the US while George was born in Italy: George, age 40, arrived in 189?, alien Margaret, age 31, born NY Mariano, age 7, born NY Anthony, age 6, born NY C. Rachele, age 4, born NY J. George, age 2, born NY A. Rose, age 1 month, born NY Living next door was George's father and mother: Mariano, age 62, arrived 1899 Rachele, age 56, arrived 1901 Daisey, age 27, arrived 1901 Elisa Dom???? (cannot make out), daughter, age 25, arrived 1901 Victor Dom????, son-in-law, arrived 1908, naturalized 1916 Concetta, granddaughter, age 2 Michael, grandson, age 2 months There is also an Oswald listed at another address that is also a son, and in 1910 there was a John listed as well.
Now Margaret is listed as Margurita Di Palma born in NY in the 1910 census. She is living with her brother, Donato.Her age is listed at 23.She was also listed with Donato in 1910 census.He is listed there as "James".Apparently her parents are dead or returned to Italy. Donato arrived in 1878.According to the 1900 census, Donato was born in July of 1876 and Margurita was born in NY in July of 1886. As the 1890 census was destroyed, it is impossible to find her earlier in the census.However, according to the 1900 census, Donato is a naturalized citizen.If you get copies of his naturalization papers, you will find out where he and his parents came from, the name of his parents most likely, and the ship he arrived on in the US.
Couldnot find the arrival of George either, though most of that name started in Minturno, a city close to the west coast near the Golfo di Gaeta, north of Naples.
