Welcome to GenealogyCloud™ (Powered by OneGreatFamily)

GenealogyCloud is a full featured API that provides access to a complete web-based genealogy family tree backend system.  This web service provides all the functionality for building, editing, searching, sharing and managing a family tree.

The web service allows you to access all of the power of OneGreatFamily.  So, in addition to basic family tree functionality like create an individual, add a father, add a child, etc., you get access to capabilities not available anywhere else, including:

·         View Preservation

·         Automated Matching

·         Merging

·        Group Architecture
