I making a site of microsoft word for school and i have to have multiple pages how do i do that?

You give each page a different name. Generally the homepage by default if usually called index.html. Each page for each family member would have a different name. Because they are family members you can just use their names like Kim.html etc. You want to be sure to have links to all the pages on your homepage. The easiest way to make it all look seamless is to use the same page design and just modify the text this way it will still feel like its all one website and you're just going through different pages.
