If one is living with another, but not legally married, a dotted line is used instead of a whole one to connect the two. Children hang down from the joining line of the parents, oldest to youngest from left to right. If there are too many children a single line can be drawn from the parents and then to other one with all the children. This is to save space if needed. Foster or adopted children hang down from a dotted line.
Twins hang from the same spot in a triangle, and identical twins are then connected as well.
Names are usually directly below each square or circle. If you do not know about your biological family, discuss the characteristics of your adoptive family. Additionally, if this information may not be available for all family members, do the best you can and comment on the relevance of not having this information. All information on your assignments is strictly confidential. Submit the assignment with the cover sheet.
