Bouldin
A surname most likely derived from a medieval personal name, with spelling shaped over time in English-speaking countries.
The #8,761 most common surname in the United States (2010 Census) — about 1 in every 82,464 Americans shares it.
Etymology
Bouldin is usually treated as a variant spelling that developed from a medieval personal name rather than from a place name or occupation. It is likely connected with older forms such as Baldwin, whose Germanic roots mean “bold friend” or “brave friend” (from elements meaning “bold” and “friend”). Over time, pronunciation and spelling shifted in records, producing forms like Boulden, Bouldin, and related variants.
History
The surname is found mainly in English-speaking countries, especially the United States, where several spelling variants were preserved by local recordkeeping. In many cases, families with this name may descend from lineages recorded under Baldwin or a closely related form. Because the spelling is variable, some branches may not share a single recent origin.

Fun fact
Spelling shifts like -win to -din or -den were common in older records, so apparently different surnames can sometimes be historically related.
