So, here they are:
Elizabeth Lansa Button; born December 11, 2007
Sadie Addis Button; born October 11, 2009
Lansa (pronounced Lahn-sa) is from the girls' family name Wolansa. We just lopped off the first two letters (stating the obvious), made up a whole new name and decided it worked. We had hoped to give Lizzie her birthmother's name as a middle name but were never able to find out what it was. Addis is in honor of Addis Wolde. They may each get another name (Elizabeth Lansa Caribou Button; Sadie Addis Starbucks Button) if Sadie keeps up her current nighttime feeding schedule but hopefully the official announcement will come before we resort to that.
