Of course the Italians and Irish stood together. They had common experiences, common aspirations and common foes. Irish and Italians ended up working together politically and socially.
In what city(ies) common experiences? The Irish were unionizing the trades, and some Italians became scab labor. The Irish were loyal to the Democratic Party, and some Italians then became Republicans. The Irish sent their children to Parochial school, and many Italians sent their children to public schools. They sometimes promulgated pejorative canards about each other's ethnicity.
There might be more small businesses with Jewish and Italian shared owners, than Irish and Italian shared owners.
They are both Catholic. However, more Irish married males go to Church, I believe, than Italian married males.
The Irish (Americans) have a tradition of going into the military as a career; not so I believe with Italian Americans.
The Irish built the American Catholic Church. The Italians did not.
These two ethnicities have their own cultures and cuisines. They tend to be most comfortable in their own respective culture.
The only interesting thing is that Saint Patrick was a Roman.
