Calkins
A surname most likely developed as a variant of Caulkins, itself probably from a nickname or regional form built on an older personal name or byname.
The #3,876 most common surname in the United States (2010 Census) — about 1 in every 33,757 Americans shares it.
Etymology
The historical evidence here points more to spelling variation than to a clearly separate root. Calkins is closely associated with Caulkins/Caulking in older New England records, and the name was being treated as one of several family-name spellings in the 19th century. The deeper origin of Caulkins is not certain from the excerpts alone, but it is usually explained as an English surname with a nickname-like or patronymic background rather than from a place-name or occupation.
History
In colonial and post-colonial New England, the name appears in several spellings, including Caulkins, Calking, and Calkins. The Bowditch excerpt shows it among surnames in Connecticut and Massachusetts contexts, suggesting an established regional family cluster. The surname remains relatively uncommon in the United States today but is still concentrated in English-speaking North America.

Fun fact
The 1861 excerpt groups Calkins with other surname spellings that were already well established in New England, showing how fluid spelling could be in early American records.
