Dulin
A surname with several possible roots, most likely a reduced or altered form of a French or English family name.
The #8,287 most common surname in the United States (2010 Census) — about 1 in every 77,225 Americans shares it.
Etymology
Dulin is not a surname with a single, universally agreed derivation. In English-speaking records it is often treated as a surname that may have developed from a shortened or altered earlier family name, possibly influenced by French naming patterns. The ending -in can reflect a diminutive or patronymic-style formation in French, but the exact original personal name or place-name behind Dulin is uncertain.
History
The name appears in Anglophone records in forms that suggest later spelling stabilization rather than a very old, fixed medieval surname. It is found in the United States at modest levels, which is consistent with a name that may have arrived through migration and then diversified in spelling. Because the evidence is mixed, genealogical lines with this surname may need to be traced by locality and earliest recorded forms rather than by one assumed origin.

Fun fact
Because the surname is relatively uncommon and its origin is uncertain, the oldest local spellings in a family line can be more informative than the modern form.
