Trombley
A surname most likely tracing back to a place-name or family form that entered English in altered spelling.
The #5,074 most common surname in the United States (2010 Census) — about 1 in every 44,694 Americans shares it.
Etymology
Trombley is not a standard dictionary surname with a single secure derivation, so its origin is best treated cautiously. It is likely a later spelling variant of a place-based or family-name form, probably influenced by French and English pronunciation habits. In North America, surnames of this shape are often altered spellings of older names that were simplified or reshaped after migration.
History
The name is found mainly in North America, especially in the United States and Canada, where many surnames were regularized or respelled over time. Trombley may represent a local or family-specific variant rather than a long-established standardized surname. Because the form is uncommon, separate lines of descent may not all share exactly the same origin.

Fun fact
The ending -ley is common in English surnames, but in North America it can also appear in names that were reshaped from quite different originals, making one spelling hide several histories.
