Baby Name: Thong

The decades-long Vietnam War — which began as a civil war in the 1950s and grew into a proxy war between the United States and the Soviet Union in the 1960s — ended with a North Vietnamese victory in the spring of 1975.

After the fall of Saigon, an estimated 130,000 Vietnamese refugees were evacuated to the U.S.

This influx of Vietnamese immigrants had a considerable impact on U.S. baby names. Dozens of Vietnamese names debuted in the SSA data in the mid-1970s. Here’s what I’ve spotted so far:

Significantly, two of the top choices for baby boys in 1975 were Viet and Nam. (In the name of the country, the element viet refers to the ancient kingdom of Yue and the element nam means “south.”) Viet was the highest-debuting boy name of the year, in fact.

Another 1975 debut name, Chaffee, is likely a reference to Fort Chaffee, one of the centers at which Vietnamese refugees were processed.

A second wave of Vietnamese immigration, which involved several million people fleeing “communist re-education camps and the 1979 Chinese invasion of Vietnam,” began in 1978 and lasted until the mid-1980s.

Many more Vietnamese names began appearing in the U.S. data as a result:

• 1977: Hang, Hue, Huyen, Khai, Lam, Nga, Oanh, Phuc, Quyen, Thien, Truong, Uyen, Xuan
• 1978: Duong, Duy, Thinh, Thuhuong, Toan, Tu
• 1979: Dat, Duyen, Khang, Khoi, Loc, Mylinh, Nguyet, Nhan, Nhi, Phuoc, Thuan, Thy, Trong, Vang, Vuong
• 1980: Chinh, Chuong, Danh, Dao, Diem, Hiep, Huan, Khuong, Kiet, Kieu, Kimanh, Manh, Mao, Nghi, Nhu, Nhung, Phu, Phung, Quy, Quynh, Tho, Truc, Tuyen, Vong
• 1981: Diep, Giang, Khiem, Liem, Nghia, Nhat, Nhut, Phan, Phat, Thuthuy, Trieu,
• 1982: Chanh, Dinh, Dzung, Dzuy, Hoai, Hoan, Kha, Kien, Lieu, Luu, Myphuong, Ngan, Suong, Thach, Thuong, Thuytrang

Most of these names reached peak usage during the ’80s.

P.S. Please note that many of the names above (such as An, Bao, Dai, Hai, Hao, Hong, Huan, Long, Mao, My, Phan, Phuong, Tan, Tu, Vong, and Yun) are also used by people of other cultures (e.g., Chinese, Hmong, Laotian, Cambodian, Japanese). Also, the name Thuy debuting a year early may reflect the fact that over 14,000 Vietnamese immigrants entered the U.S. during the first half of the ’70s — before the fall of Saigon.
