Gambill
A surname most likely developed from a nickname or old personal name, with English and Germanic-style forms possible.
The #7,835 most common surname in the United States (2010 Census) — about 1 in every 73,041 Americans shares it.
Etymology
Gambill is not a transparent modern English word, so its origin is not certain. It is likely one of those surnames that began as a nickname, a reduced form of a personal name, or a regional spelling that was later stabilized in English-speaking countries. Because the sound and spelling do not point cleanly to a single well-attested source, the safest explanation is that it arose from an older Germanic or English family-name form that has since been altered in transmission.
History
The surname is found in the United States, where many such names were reshaped by spelling variation, migration, and local pronunciation. In records, names like Gambill often appear beside similar forms such as Gamble or Gambil/Gambel, but a direct lineage is not always demonstrable from surname alone. Its modern distribution suggests long-established Anglo-American use rather than a clearly traceable single medieval source.

Fun fact
Because surnames like this often changed spelling across generations, one family may preserve several different written forms in old records even when the spoken name stayed the same.
