Introduction

Ancestor Tree Manager (ATM) is a free genealogy program which enables you to create a website for publication of family trees, person pages, scans of sources and an index on persons.

  • ATM is available for Windows, Linux and macOS
  • The program can run in English, Dutch and German
  • While the program is running, you can switch between languages
  • Reports can be generated in English, Dutch, German, French and Norwegian
  • The manual is available in English and Dutch
    (from version 11.0 the manual is included with the program, for version 10.1 it is currently still on the website but will be removed in 2025)
  • The program is simple and intuitive
  • Just like with a word processor, edits can be easily undone
  • There is very good support for linking material
  • Many useful functions are available for checking and maintenance of the database
  • A separate File Transfer Handler is included, with which the reporting can be transferred to the internet


ATM is developed by an enthousiastic amateur genealogist with a professional IT background.
