Basic Symbols:
Individuals:
Square: Represents a male individual.
Circle: Represents a female individual.
Marriages:
Horizontal Line: Connects a square and a circle to indicate a marriage or partnership.
Children:
Vertical Lines: Connect downward from the horizontal marriage line to represent children.
Detailed Symbols:
Deceased Individuals:
X through the Symbol: Indicates that the person has passed away. For example, a square or circle with an “X” through it.
Adopted Members:
Dashed Line: A dashed vertical line connecting to a horizontal marriage line indicates an adopted child.
Divorced Individuals:
Two Parallel Lines: Sometimes used to indicate that the parents are divorced.
Unmarried Partners:
Diagonal Lines: Sometimes a diagonal line through the horizontal marriage line is used to indicate an unmarried partnership.
Additional Information:
Parentheses or Footnotes: Often used to include birth and death dates or other relevant details.
Color Coding (Optional):
