Precise comparative statistics are hard to come by, and experts say there was most likely no one precise moment when the practice fell off. It began to decline within the last few decades, they say, and the evidence of its rarity, if not formally quantified, can be found in almost any American courthouse.

The New York Times examined the more than 500 applications for name changes in June at the Civil Court in New York, which has a greater foreign-born population than any other city in the United States. Only a half dozen or so of those applications appeared to be obviously intended to Anglicize or abbreviate the surnames that immigrants or their families arrived with from Latin America or Asia. (A few Russians and Eastern Europeans did, but about as many embraced their family’s original surnames as adopted new ones.)

The vast majority of people with clearly ethnic surnames who applied to change them did so as a result of marriage (belatedly adopting a spouse’s surname or creating a new hyphenated one) or childbirth (because they were legally identified when they were born only as a male or female child or were adopting a parent’s name).

Iyata Ishimabet Maini Valdene Archibald of Brooklyn changed her name to Ishimabet Makini Valdene Bryce. Guo Wi Chan of Forest Hills, Queens, changed his to Ryan Guowei Chan. And after Jing Qiu Wu, the Flushing, Queens, mother of 5-year-old Star Jing Garcia, divorced, she renamed her daughter Star Rain Wu, dropping her husband’s surname.

Several dropped Mohammed as a first name, adopting Najmul or Hayat instead. And one older couple changed their last name from Islam to Khan, but they said they were conforming to other younger family members rather than reacting to discrimination.
