From Robbie J Akins:
ScionPC is free, fully-featured, genealogy software with a modern, easy-to-use interface, ideal for both the novice and the experienced genealogist. Databases from other family tree programs can be imported into ScionPC using its GEDCOM import facility. Just export your data from your old program as a GEDCOM file and then import that file into ScionPC. ScionPC will also directly load databases created with Amiga versions of Scion. The program has been written in a totally secular manner, has no checking on sex (to allow for "unconventional" relationships), and has no naming constraints (to allow for adopted children). The partners of a family group (or marriage/union) are referred to as "Prime" and "Partner" rather than "Husband & Wife" or "Father and Mother". Either partner can be the Prime. Free-form notes and sources can be created and viewed, and any files may be attached to any person or family.
