I started a family tree about two years ago with my oldest living Aunt. She has Alzheimer’s now and that got me back to work on the tree. One problem I have is with unorthodox births. Where there may be birth and adoptive parents. Or children that are half related. My Father’s father was his birth father. His father’s wife was his adopted mother. But he also knew his birth mother. I have not been able to list the birth and adopted mothers in a single line for him. Also his brother shared the same mother but a different father. How do I attach them both to the same mother but different fathers? Family Tree Maker seems designed for the “traditional” family tree. But throughout history there have been many variations and complications to the norm.
