A few of these types of markers from many immigrant groups make it into the host language; others become extinguished, or are characterized as folklore. My grandparents, both born here from immigrants, used traces of Irish and Scottish.
As one example, the great Scottish migration to the U.S. in the 1840s inserted the letter "a" before a verb to signify the immediate future, or that you are presently doing the act: "I'm a-going to the house." In today's vernacular, we would say, "I'm going to go to the house" or "I'm going to the house right now." You can hear this usage in old-time songs from the colonial to Civil War era.
Down South we say, “I’m fixin’ to go to the house.”
