I think I have solved the Amalia/Amelia dilemma. I looked up all the German records for her on familysearch.org from the Mormon Church. Every entry shows her name as Amalia. It is only after she came to America that the spelling starting going all over the place.
Plus, I found some old notes on the Ensele's and even my Dad called her Grandma Amalia.
So there, one more clue in this huge jigsaw puzzle.
