Kinship Chart

Ever wonder “what is a second cousin twice removed?” Use the chart below to find out.

For a true family relationship to exist, there must be a common ancestor. The common ancestor is located at column1, row1, as shown in the chart below. Find the relationship of one person to the common ancestor in column one (1), under “Common Ancestor,” then find the relationship of the second person to the common ancestor along row one (1). Follow that row across to meet the column of the first person. The relationship of the two people is shown where the column for the first person and the row for the second person intersect.

For example, you find out that your great-grandfather is also the great-great-great grandfather of another relative. Follow row4 (for great-grandchild — you) to where it intersects with column6 (great-great-great-grandchild, labeled 3rd Great Grandchild — your relative). Voila! You are second cousins twice removed. Mystery solved.

More Notes on Relationships

  • Your first cousins are those people in your family who have two of the same grandparents as you, i.e., they are the children of your aunts and uncles.
  • Your second cousins are the people in your family who have the same great-grandparents as you, but not the same grandparents.
  • Your third cousins have the same great-great-grandparents, and so on.
  • Tip: The Relationship charts in the Family Tree pages on this site indicate relationships between cousins, for example, as 1x, 2x, 3x, etc. What 1x refers to is your 1st cousin, 2x indicates your 2nd cousin, and so on.

When the word “removed” is used to describe a relationship, it means that the two related people are from different generations:

  • You and your first cousins are in the same generation (both two generations younger than your grandparents).
  • Your mother’s first cousin is only one generation younger than those same grandparents, so your mother’s first cousin is your first cousin, once removed.
