Isabelle is a classic, a variant on the uberpopular Isabella. It means pledged to God, and is currently the 128th most popular name in the U.S., while Isabella sits in the third spot. It's a classic that's never fallen out of the top 1000, and is currently on a huge upswing, along with all the other elle and ella names.
Amarachi seems to be a hybrid name from Nigeria, a combination of Amara, which means grace, and Chi, which means spirit. It's a lovely name, and a nice homage to her daddy's heritage.
In all, two beautiful name choices, but a bit of a tongue twister when you include Asomugha into the mix!
What do you think of Isabelle Amarachi? Would you consider either of the names for your daughter?
