As a newbie myself to WikiTree my advice is to wait a bit before importing. Build your immediate tree back a few generations - get familiar with sourcing and citations- search for family members, they may already be there. And read G2G posts, look at related posts and read every help page you can. WikiTree can be confusing - but there is a huge community willing to help. You'll love being here :) but start out slow. And welcome to WikiTree!
