What is this tool for?

Descendant Tree Maker is a practical genealogy tool for creating clean and structured descendant charts directly in your browser. It allows you to build a visual descendant tree starting from a central person or couple and extending through multiple generations. As you enter names and years, the tree updates instantly into a balanced printable layout.

The tool supports up to 7 generations of descendants (target couple / person included) and allows you to add spouses or partners for each descendant. You can also choose which person in each couple continues the bloodline connection so descendant lines remain visually accurate even in more complex family structures.

All names, birth years, death years, and marriage dates are fully editable. Empty boxes are supported for unknown relatives, which makes the tool suitable for real genealogy research where information may be incomplete. The layout, spacing, and connectors are generated automatically, so no manual positioning or drawing is needed.

To start, simply open the standalone HTML file in your browser. Enter family information on the left side and the live descendant tree preview updates instantly on the right side. You can scroll horizontally and vertically to view larger trees.

The tool also includes JSON import and export features, allowing you to save your descendant tree data and continue editing later. Example data can be loaded instantly to demonstrate how the layout works.

When finished, export the tree as a high-resolution printable JPEG image. Export resolution automatically scales based on the size of the tree, making the tool suitable for both standard home printing and large professional prints.

This tool works completely offline and does not require installation, subscriptions, Excel, Word, or any external software. It is compatible with both Windows and Mac computers and works directly in modern web browsers.

Descendant Tree Maker is suitable for genealogy research, documenting family history, creating printable descendant charts, and preparing meaningful family records that can be shared or displayed.
