If you've ever tried to use Find A Grave to track down an entire family, it can be a frustrating experience. Siblings can buried several states apart - making a search for their cemetery difficult, if not impossible. Linking your family together prove to be a huge help not only for you but also for any researcher studying your family. It's always easier to click a few links to find relatives.
You can link families together in a few ways. Start by entering the gravestones for all your relatives. Once you've done that and have a memorial number, enter that number in the appropriate parent or child categories. Someone looking at that memorial will be able to quickly click through to the next relative. You can also create a virtual cemetery, listing all the memorials for a family.
If you're a Find A Grave researcher, take the time to finish these few steps. It's worth it in ease of research.
