German Naming Patterns

According to a Mennonite Historical Society book (genealogy), it's common for German immigrants in the US to have used, however loosely, a particular pattern for naming their children:

Sons:	Daughters:
1st son--named for the paternal grandfather 2nd son--named for the maternal grandfather 3rd son--named for the father 4th son--named for the father's eldest brother	1st daughter--named for the maternal grandmother 2nd daughter--named for the paternal grandmother 3rd daughter--named for the mother 4th daughter--named for the mother's eldest sister

Almost funny that it was a tradition--sure would make for a lot of cousins with the same name!
