I see from your family tree that your India Amelia Cage was in Oberlin, Lorain Co. Ohio in 1850. If that is the case, then her father was Albert Gallatin Cage (ca. 1796-1850) of Terrebonne Parish Louisiana. If you're familiar with Google Books [http://books.google.com/books
], go there and search for a book called "Reminiscences of Levi Coffin" and read pages 477-481. I think the Cage children whose story is told there are the same ones you are looking for. If so, these are definitely the children of Albert Gallatin Cage. I've found a few other of what I believe were Amelia's siblings: Andrew (b. ca. 1830), Adaline (b. ca. 1836), Antoinette (b. ca. 1839), and Delia Ann (b. ca. 1841). If any of this sounds correct, I think I can fill in some of the blanks for you.
