I have really hit a brick wall. I have located the Brown Family on the 1900 census for Dallas County, TX, but don't see them on any other census records. Any guidance on how to track the family will be greatly appreciated.

Brown, Peter B/M/GA
Brown, Georgia, B/F/LA
Brown, Henrietta B/F/TX
Brown, Elizabeth B/F/TX
Brown, Peter B/M/TX
Brown, Carrie B/M/TX
Brown, Obed B/M/TX
Brown, Clyde B/M/TX
Brown, Mandy B/F/TX

Family stories suggest that some of the family members spent time in Oklahoma, California, and Phoenix.

Thank you.
