Hi. Welcome to Wikipedia, and thanks for working to improve the site with your edit to List of people from Union City, New Jersey, as we really appreciate your participation. However, the edit had to be reverted, because Wikipedia cannot accept unsourced material or original research. This includes material lacking cited sources, or obtained through personal knowledge or unpublished synthesis of previously published material. Wikipedia requires that all material added to articles be accompanied by reliable, verifiable, secondary sources explicitly cited in the text in the form of an inline citation, which you can learn to make here.
Regarding notability, while notability is the standard for determining whether a person merits their own article, such sources should are also needed to justify whether someone without an article merits inclusion in a list-type article or section, as as the aforementioned one.
If you have any other questions about editing, or need help regarding the site's policies, just let me know by leaving a message for me in a new section at the bottom of my talk page. Thanks. :-) Nightscream (talk) 03:05, 19 May 2012 (UTC)
