🔧 How to Use the Family Tree Calculator (Step-by-Step)

Using the Family Tree Calculator is straightforward. Here’s how to use it:

In the field labeled “Person’s Name”, enter the name of the primary individual you want to connect in the family tree.

  • Mother
  • Brother
  • Sister
  • Son
  • Daughter
  • Grandfather
  • Grandmother
  • Uncle
  • Aunt
  • Cousin

3. Enter the Related Person’s Name

Next, enter the name of the second person in the “Related Person’s Name” field.

4. Click “Calculate”

Press the “Calculate” button. The tool will immediately display the relationship between the two individuals in a clear sentence, such as:

“John is the uncle of Sarah.”

5. Reset if Needed

If you want to start over, simply click the “Reset” button to clear the form and try a new relationship.

📘 Real-Life Example: Understanding Family Connections

Let’s say you’re building a family tree and you want to document the relationship between two people—Sarah and John.

Example:

  • Person’s Name: Sarah
  • Relation Type: Uncle
