Simple, flexible family tree software?

[teragram31510]

I use RootsMagic.
You choose to link to Ancestry, FamilySearch or MyHeritage - or you can (like me!) choose not to link

There is a free version, RootsMagic Essentials, but the full version has greater functionality.
But worth trying Essentials to see how you get on.

After reading another thread on RootsChat a few weeks ago I decided to try RootsMagicEssentials and it suited me - so I was "given" the full version for Christmas. Like KGarrad I don't link to anything and add my own sources (photos of certificates, of gravestones etc. ) as I choose. It's not at all expensive for the complexity it seems to allow - and I'm not a techie by any means but I manage - so far!
