The first form we have to change is the birth certificate. When my daughter was born, we knew that she was going to have 4 names (2 given, 2 surnames). My wife is from the Philippines, and it is typical there to have 1 or more given names, and then maternal surname and paternal surname. It is common for people to have several names (e.g. the signer Sheree is actually Cherry Hazel Sweet Fae Bautista Augustin). Unfortunately the birth certificate only had first, middle, last. We didn't want to hyphenate the last name so we had to either have a 2 word first name or middle name. In the end, we went with 2 names for the first name, maternal surname as middle name, and paternal surname as last name.
