First of all, sorry for your loss. When my dad passed away I sat down to write a few notes to help the minister, and ended up pretty much writing the eulogy for him. Start with the factual stuff, e.g. Where and when she was born, her parents, any siblings How she met your dad, wedding etc When you and any siblings were born Work life if she had one Then on to interests, holidays, any wee stories or memories you or family or friends want to share. If you aren't used to standing up and speaking in front of folk, my advice would be either to pick one person and speak as if you are talking to them, or pick a spot on a wall or something and talk to it.
