According to etymology, the idiom “how come” is a short form of “how does it come to be?” The earliest reference in the Oxford English Dictionary (OED) for the idiom “how come” appears in Bartlett’s Dictionary of Americanisms, published in 1848. Although the OED claims that “how come” was invented in the United States, Bartlett’s article shows that it was coined in England. It reads, “Doubtless an English phrase, brought over by the original settlers.“
Whether or not “how come” came from the United States, it is far more popular in American English than in British English.
There are several different older records of the phrase available which claim to be the oldest. But the fact remains that the phrase began to appear in print as early as the 1500s. A search in Google Books confirms it. Since most of the books are from England, it reinforces the fact that the idiom actually originated in England and later became more common in America.
