Welcome to WikiTree, Charmaine! We’re glad to have you join us! I see you already have a few tags of names you’re following. And you’ve found the perfect place to ask all your questions: here on G2G.
Two suggestions for you:
1) Go slowly! Getting it right the first time will save you hours later.
2) Ask, ask, ask. You’ll find a whole host of folks willing to help you out.
I hope your experience here in WikiTree will be as fruitful as mine has been.
