What you do is make a family template. Put two or more numbers in, for their names. I'll fill it in with the secret names, heheheh! You can have as many family members as you want! Girls are: 1-76. Boys are 1-73.
Here is an example:
LN: Dawson
DH: 34, 56
DW: 22,65
DD: 45,12
DS: 62, 44
Then I'll give them names! :) Have Fun!
