Rhoda is the key. In one tree, she's the gg-gm of a John Curtis Rowe, d 1994. And she marries an Avery.
In the other tree, she's born into an Avery family.
Options are
1 - true story, one girl, Rhoda Emeline (Avery) Avery
2 - two Rhodas
3 - one of the Rhodas didn't exist, she was created out of internet confusion.
I dunno. But the other answers should fall out from this one, because the Emelines are only there to produce William Randall Avery's wife.
