Alternative Family Trees for Adoptive Families

It comes up in the school setting quite a bit, but even adult adoptees face questions when tracing their family tree and displaying the results. Do I trace my genetic roots or my adoptive family's history? What if I want to do both? The usual printed family tree chart has blanks for one mother, one father, and their ancestors, but no spaces for adoptive, foster, or step parents and their ancestors - not a great fit for many of today's blended families. There are a number of alternatives, however, some of which I address in How to Handle Adoption in the Family Tree. If you have additional suggestions, please add them in the comments below!
