Canaday
A surname of uncertain origin, probably a variant spelling built from an older personal or place-name form.
The #9,375 most common surname in the United States (2010 Census) — about 1 in every 88,976 Americans shares it.
Etymology
Canaday is usually treated as a variant spelling rather than a surname with a single, secure origin. It may reflect an old English or Irish form that was reshaped in spelling over time, possibly influenced by pronunciation and local record-keeping. Because the surname is relatively uncommon and early records are sparse, its exact root is not firmly established.
History
The name is found mainly in English-speaking countries, especially the United States, where many rare surnames were stabilized only after migration and repeated clerical spellings. In some families it may be connected to older forms such as Canday, Canada, or other similar-sounding names, but the evidence is not strong enough to make one derivation certain. As with many uncommon surnames, different family lines may have different origins.

Fun fact
Because the surname is so spellable in several ways, the same family line can appear under different forms in census, church, and county records.
