Most people open MyOrigins the first time not sure where to start. That hesitation is normal - "tell me about your family" is such an open question that it is hard to know which thread to pull first. A little preparation beforehand turns that vague starting point into a conversation with real momentum.
Before your first session, it helps to have two or three specific things in mind: a name you have always wondered about, a story you half-remember being told, or a document sitting in a drawer you have never really looked at closely. Any one of these gives the interview something concrete to research while you talk.
You do not need dates or certainty. "I think my grandmother's family came from somewhere in Missouri, but I am not sure" is a perfectly good starting point - it is exactly the kind of lead the research engine is built to chase down and confirm or correct.
A few prompts worth sitting with beforehand: Who is the person in your family you know the least about? Is there a story that gets told at gatherings that nobody has ever written down? Do you have a box, a bible, or an old letter you have never had a reason to open? Each of these tends to open up a session far more than starting cold.
