Decipher the last name written on this Orangeburg, South Carolina, USA record

[AncestryCompassResearch]

Incidentally the South Carolina death indexes include a Roland Sinns in the listings for 1915-1924

Don't know if you can search the Agricultural Schedules by farmer and try Sinns as a surname, I couldn't access the relevant archives to try, see state by state entry for site address.

Thank you for this information and thanks to all those who contributed and are following this thread.
At this point I am following several paths with different spellings just so i don't miss Isaac's siblings or parents. Sinns is a path as well.

I'll post my findings here and continue to search Isaac and "Satyra - Sotara".
Both are my paternal ancestors.

I came across these records and what looks to be the same Gavin Pou (Pow) who moved to Alabama.

   The only thing that made sense to me, is that Carson was Satara's maiden name, with the father Isaac Senn within or out of wedlock, then she is now married to a Pon/Pou. ( informant, ( his son?) wasn't thinking maiden name)
   Nothing to back this up, though...Isaac Senn is elusive despite trying several alternative spellings.

I did, however, find an Isaac Sen freed man -  Occ  plantation worker for one yr 
16 Jan 1866 to Jan 1 1868 signed ? Dantzler Orangeburg, South Carolina, United States 
Hit arrows to the right for his contract - He signed with an x

adding:
a tree came up for Isaac & Satyra, with a daughter for them as well.
Also an age for Isaac but he's not visible on any S.C. census...
The census info attached to her is too complicated for me to absorb.

Might be your ancestor's plantation he worked on as a free man???

also found this interesting answer to another online query-

That answer above was certainly a good hypothesis, given the Pou/Carson/Livingston proximity. How to prove, though, when they are unnamed on census like "property"?
   For other's searching...as per the poster's findings ( see images attached above) above:
   If this is the correct Pou family, you can see who the ancestors are claimed to be by scrolling down & hitting on the father's names...goes back to Gavin Pou of Scotland (no stone) all buried Orangeburg cemeteries.
