I don't know about Sarah Anna Wood, but Levi's parents were Levi Alexander Coen and Delilah Brewer. The info I have says that Sarah died, or was separated from Levi, soon after. Levi Carlton married Anna Hower on 15 May 1873.

Levi Sr was the son of Eli Coen and Martha, or Marsha, Coen. He was born in Monroe Co. Ohio in 1810, and died in 1889 in Ansley, Custer Co., Nebraska.

I have a fairly extensive pedigree for Delilah Brewer. It goes back to 1000 or so, but I have no idea of its authenticity.
