Thanks for replying Falkryn. To address your points:
1. I have a laptop, using windows 7.
2. That sounds ok to me.
3. In Gedview can you amend or add to your tree, or is it just to view?
4. Do you photograph documents in situ, and if so, can you incorporate the photos into your tree on the ipad?
So sorry if I am asking stupid questions! I am a bit of a Luddite; actually that's not true, I do try to keep up with technology but it changes so rapidly!
