According to a 1995 "New York Times" "Streetscapes" article by Christopher Gray, the census taker who visited the Irish-born McSorley in 1880 recorded the year the founder of the pub first arrived in the United States as 1855, but immigration records show that he arrived on January 23, 1851, at the age of 18, accompanied by Mary McSorley, who was 16. When confronted with the fact that the 1880 census did not contain this entry, Gray corrected it to 1900 in his book. John McSorley first appeared in city directories in 1862, and the building his bar occupies was built no earlier than 1858, according to city records.
