Hi Sandi,
If your asking how we would know if the information on Travis Carter's profile is correct, my answer to that is - we don't. There are no supporting sources attached to prove the details. Research is needed to find documents like birth, marriage, census etc.
You could ask in G2G for help finding some sources for Travis.
These help pages are a good way to learn about research and sources
