It looks like an “od” in between the names of John H Gronewald and Cornelia M Albers on this document from her 1880-era homestead claim in Dawson County, Nebraska. It clearly is not.
It’s “vs” for “versus.”
While the ending “s” is atypical, it is clear that the scribe wrote his ending “s”s in that fashion–after all that’s how the “s” in Albers appears as well.
It’s not “od.” I should not transcribe it as “od.”
Looks can be deceiving and transcribers have to also look at intent and not be entirely literal.
