What you posted is not a document, it is a transcript of something published in a book.

Locate the book and look in the introduction to see what the source is, then get a copy of the original document. It may tell you more, such as whether the Company was in the Virginia Regiment or was a militia unit raised temporarily.

While you are looking at the book, be sure to write down author, title, publication data.
