Barbara, I am not researching this family, but since you mentioned that not much is available other than the tax record info, have you checked out the 1850 Census for Hampshire Co. on the Mineral Co. web page at http://www.rootsweb.com/~wvminera/census.html? There are Brelsford's and Brellsford's listed. When you go to the site, click on the 1850 Census and be patient; it is a very big site and takes a minute or two to download the index completely. Beneath the page number section is an alphabetical index.
