There definitely was a hamlet of Carlin, South Dakota. And
there were also three other Carlin places in South Dakota:
* Carlin Flats
* Carlin Bottom, and
* Carlin Draw
I was researching my Carlins, I think on
Ancestry.com during its free
access period (which runs through the end of this month), and found many
of the hits that came up when I entered "last name: Carlin" were for
people in towns named Carlin. I think the records were military (maybe
civil war) pension files. You might want to do an advanced search for
"Carlin" in different time periods...you'll probably find enough to add
to/confirm what's on your pages.
Happy hunting!
