    Are there any historical photos from the mid to late 1800’s of the mounted militia? My husband’s great grandfather, Paolo (a.k.a. Paolino) Amico was a resident of Delia. On his death record, at age 48, in February of 1885, it stated he was a mounted militia. I wonder if group or individual photos may be available from that time frame.

  2. Jim says:

    My dad’s father Alphonso LaDelia came to the state when he was 13, I think. It would have been around 1911. I am wondering if he was given this name because he didn’t understand English. I knew he was born around Caltinestta. I just found out there was a town near there called Delia. I hope to visit, and see if I have any family there.

  3. George says:

    I, George am the American grandson of Giacinto Gallo, born 1887 in Delia. It is known that there was a Luigi Gallo that was my great grandparent. Believing that
    Giacinto was the firstborn son and knowing how rigid was adherence to the naming convention it is expected that Luigi would have been a son of an earlier Giacinto, and thus my great great grandparent having lived from about 1830 as a Contadino in Delia. I wish to learn the surnames of the spouses of any of the above.

    Looking for palumbo

  5. George says:

    I understand that five most common surnames in Delia Caltanissetta are Genova, Gallo, Banchieri, Strazzeri & Borzellino, and I think on that order. Hundreds for Gallo in fact. Yet those do not turn up in the most prominent list of Greater Caltanissetta. Curious!

  6. George says:

    I don’t see a pin for Reano searching yet, but only one for Pinerolo. Hoping the COVID has not made difficulty for you.

  7. Sheryl says:

    I am trying to find birth and marriage records for my family, named Cosentino. I previously had photos of church records but they got lost in our move. My Great grandfather’s name was Constantino Cosentino and my great grandmother’s name was Rocca (Rose) Diglioria. They were both from Caltanissetta Sicily. I believe my great grandfather worked in the salt mines.

    • George says:

      Hello Sheryl. I am in USA but understand that Vaughn Canada is a place full of Deliani expatriates. I am told this by a DNA 3rd cousin of mine whose ancestry includes the name Cosentino.

  8. Alicia says:

    I am looking for someone to help me build my family tree further, which I have currently come to a road block as of right now. I have created a family tree on and I can’t seem to find more of my maternal lineage which I know goes back to Delia, Caltanissetta from Canada, where I currently was born and where I currently reside. My mother’s maiden surname is Cosentino, which I know is a predominately Calabrese surname but I know our family is from Sicily, but I don’t know if they could have immigrated over from Calabria or anywhere else.
    If there is someone who could help me with this and to discuss next steps in the process that would be greatly appreciated.

    Thank you Kindly,

    Alicia Hartsman
