Because people, believe it or not, Google/search information about others, information that can't quite be determined on other social media platforms, it's suggested that you provide as much information about who you are trying to find here.
Be as descriptive as possible down to using their correct names written in kanji, if applicable.
The more information that you give, the higher likelihood that this page would rank high enough for someone to find when doing a minimalistic background check on themselves or someone else.
With that said, keep privacy in mind too. This information will be public; everyone will see it. Therefore, you should give as much as you can, but not too much as to go beyond what you would feel comfortable with the entire world knowing.
