Hi Sharon, I'm sorry for the loss of your father. First, just take the time you need to grieve, and look after yourself. But eventually, you will want to put your father's genealogy research online. Wikitree is a great place to start and there are many of us here willing to help you as you go along. It can seem overwhelming with all that information, but I would suggest to just do a little at a time starting with your parents, then grandparents, great-grandparents and so on. It is important to preserve all your father's hard work and that it can be available for generations to come. Just do a little at a time and we are here on G2G to help you with any questions.
