Ketcham
An American surname most likely developed as a spelling variant of Ketchum, with roots in an older English personal or place-name form.
The #8,042 most common surname in the United States (2010 Census) — about 1 in every 75,029 Americans shares it.
Etymology
The surname Ketcham is generally treated as a variant spelling of Ketchum, with the final vowel and consonant simplified in American records. The deeper origin of Ketchum itself is not fully settled in the older surname literature, but it is usually linked to an English name or place-name base that was reshaped in surname form. Because the historical sources here only list Ketcham alongside related surnames and do not explain its derivation, the safest reading is that it belongs to the same surname family as Ketchum.
History
Ketcham is best known as an American surname, and the spelling appears in records alongside Ketchum and similar forms. The family name was carried by several early North American bearers, and over time the Ketcham spelling became established as an independent written form even if it began as a variant. The historical excerpt provided does not give a direct etymology, so its precise earliest origin remains uncertain.
