Christina Anne Kelleher's Family Home Page

My name is Christina Anne Kelleher, and I have just begun researching the history of my family. I am looking for information on my maternal grandmother's family, who came from Italy in the 1920's and my father's family, Irish immigrants who arrived in the U.S. sometime in the 1840's. My great-grandmother, Modestina (or Modesta)Passerelli, came from a town in Abbruzzi, Italy, and her parents names were Guiseppi and Leoricita, but beyond that I have no information about them. My great grandfather, Constantino Scervo, was from Calabria, but died in an accident in 1937 and I don't know much of anything about him yet.
My father's family has lived in the Illinois and Wisconsin area since coming to this country. The oldest ancestor who's name I have thus far is Patrick Kelleher, and I am under the understanding that it was his parents who came from Ireland, but I do not yet know who they are.
