I need to dig it out, but Roxanna is mentioned in Austin Morgan's will when he dies in 1863. The estate owes her $400.

Roxanna Huffman is still living with her sister, nieces, nephews and mother in Porter County, Indiana. Also, I believe her cousin Henry Hoffman (son of Christoph Huffman) is living with them.

1880 US Federal Census
That's it. I can't find her in the 1880 census.
I've been looking for Roxanna, leaving the name blank, born in Ohio and lived in Indiana. Roxanna isn't a very popular name around this time, so there aren't a whole lot of records. However, there isn't a marriage record in Indiana for Roxanna. Familysearch.org brings up nothing, either.
