You don't have a lot of information on your ancestors just yet, so that makes it a little hard for those who want to help to give you a hand.
I suggest reading through the following page:
This will give you some great ideas on where to find information that will help you confirm the dates and places you've added to the profiles you've created.
It's important that you add a source to back up any information you add to the profiles you create. This helps other researchers who might come along later, and it will help you when you come back later, too! :-)
Most importantly, don't be shy about asking for help. There are loads of people out here who like to help new people learn how to research their ancestors.
