Are you male or female and what DNA service did you use? I am maintaining a Brawner Y-DNA database on FTDNA.com and would love for you to contribute if you are a male. It sounds like you have taken an autosomal DNA test such as the ones offered by ancestry, 23andme or FTDNA.com. By the way, the earliest Brawners appear in Maryland back in the mid 1600's and they reportedly came over from England on the Ark and the Dove with Lord Calvert but there is no documented proof of this yet. I can give you more information on your specific line with a little more information from you.
