As people get older, their drive to find out more about their origins in China increases. But finding records and information about earlier Chinese immigrants to the United States can be daunting and unsuccessful for many reasons, not the least of which is looking in the wrong place.
While it seems natural to search for immigrants who entered on the west coast, especially San Francisco or even Seattle, there were a fair number of Chinese who crossed either the northern border from Canada or the southern border from Mexico in the days when these borders were more porous.
Using familysearch.org, a search was made for three fairly common Chinese surnames, Wong, Chin, and Yee, to see how many of them entered the U. S. from Canada between 1895 and 1956 and from Mexico between 1903 and 1957.
The figures below are inexact as a few Wongs, Chins, and Yees might not be Chinese, but probably most were. In contrast, many of the Lee immigrants crossing both borders were not Chinese so it isn't possible to give a count without examining each case individually.
from Canada from Mexico
Wong 3,610 1,794
Chin 2,903 968
Yee 1,017 542
