Hi Tessa,
I do actually have some ship manifests and the 1920 and 1930 Censuses for for my gggf and my ggf. They were the last of the family to move to the states. I'm 99% sure the ship manifest I have already found for my G-Grandfather, his mother, and 2 siblings is correct (they all traveled together in 1916). The one I am a little hesitant about is the ship manifest for my GG-Grandfather who came to the states approx. 6 years before the rest of the family.
Starting with my GG-Grandfather, the information I have received, from my grandfather via his aunt, is that his name was Giovanno Galante born in Santa Croce on Jan. 1, 1874. Once in the states the family settled in Westmoreland County, Pennsylvania. (More specifically Jeannette,PA and some ship manifests list West Jeannette as being the final destination) I know that everyone in the family took up anglicized names, so my gggf became John Galando at this point. Through Census information I've gathered that he arrived in 1910. This is where I start to get unsure of which manifest for this particular person is correct because I've found several with similar names and even names of relatives living in the states match up to information I have. I've seen Giovanno as it is written on my info, as well as Giovanni and Giovanni Antonio.
My GGF is the last Italian born person in my line (and the one I was hoping to find more information about to possibly look into Dual Citizenship). He was born Sabastiano Galante in Santa Croce on Nov. 10, 1903. The ship manifest I have for him, his mother and siblings I'm fairly sure is correct. From then on he went as Samuel Galando. I've found him on the 1920 Census with the rest of his family and then 1930 Census with his wife, first child, and sister in law. But that is it that I can find on him. I'm having trouble tracking down any kind of marriage records (wife's name is Josephine Eckenrod (Eckenrode is another possible variation). I've heard stories that they ran off just to get married since my GGM was only 16 at the time, but my grandfather isnt sure where they got married and I can't track anything down. Also my Grandfather said that Samuel did become a Naturalized Citizen, but again I haven't been able to find anything. I was helped in another thread here about some notes and stamped dates I was seeing on Ship Manifests, which we believe to be Certificates of Arrival and pointing towards family members becoming Naturalized Citizens, but my GGF is the only one in the family that does not have any of the Certificate of Arrival markings on his line.
Maybe there might be someone here that could help me track down some of this information that I'm hitting a wall on. Here is a little rundown of all the info I have on the entire Galante(Galando) family that came to the US.
Parents
-Great Great Grandfather - Giovanno Galante (John Galando) born Jan 1, 1874 in Santa Croce
-Great Great Grandmother - Maria Antonia Galante (maiden name Petrillo, anglicized name: Mary Galando) born April 12, 1874 in Santa Croce
Children
-Great Grandfather - Sabastiano Galante (Samuel Galando) born Nov. 10, 1903
-Francesco (Frank) born Sept. 18,1900 in Santa Croce
-Salvatore (seemed to have kept this name, but I have seen the spelling of Salvadore on Censuses) born Oct 12, 1908 in Santa Croce
- Giovannina (Jennie) born June 14, 1910 in Santa Croce
I listed Santa Croce as the location several times, and while I know there are several communes in Italy by this name, I've narrowed it down to being Santa Croce del Sannio, Benevento, Campania. Also as to where the family settled in the US, they stayed pretty much in either Jeannette, PA or nearby cities all within Westmoreland County.
Any help would really be appreciated, and sorry for such a long post.

I just figured that I should probably clarify what I do know as much as possible.
