Feng
A surname most often linked to Chinese family names, though the lone historical excerpt here is too noisy to pin down a specific origin with confidence.
The #3,351 most common surname in the United States (2010 Census) — about 1 in every 28,890 Americans shares it.
Etymology
In modern usage, Feng is most commonly a Chinese surname, usually written in pinyin as Feng and representing different Chinese characters with different meanings. The single historical excerpt provided does not clearly address Feng itself, so it cannot safely be used to establish a specific etymology. Because several Chinese surnames are romanized as Feng, the exact original character and literal meaning depend on the family line.
History
Feng is a well-established Chinese surname and appears in many parts of the Chinese-speaking world, including among diaspora communities. In English-language records it is often a transliteration from Mandarin pinyin, so the same spelling may represent more than one underlying Chinese surname character. The supplied source excerpt appears to be a noisy incidental mention of a different surname and does not add reliable historical detail for Feng.

Fun fact
