Christiana Brown (Adams) - Who was Ira Brown's wife?

I have two names: one from a book "the history of the town of Pittsford, VT," page 693 written 1872. where it says Christiana Adams. THE other is from find a grave which shows a grave stone, Christina wife of Ira Brown died Feb 01, 1828 age 28. BUT the paper work shows Christina Elms as wife.

There is no Birth dates, I find no connection to Adams family which were close to the Brown family, Elijah Brown married Sarah Adams.
Neither possible spouse turns up in search engines with any kind of positive evidence
