2 different Brown lines

I have two different Brown family lines, but they both married into the Goble family. the nearest is Ann Brown daughter of John Brown and Judith Ball Jamison. Ann married Benjamin F Goble and they are my 2nd great grandparents on my fathers side. They lived and died in Clark County Illinois near the border to Edgar County Illinois. John was born in what is now West Virginia but was then Berkley County Virgina. his parents were Robert and Margaret Wilson Brown. The only information I have on Margaret is that her father's name was Samuel Wilson. Robert's father was Matthew Brown born in Bucks county  Pennslysvania. he was married to Mary Throckmorton in Berkley County Virginia. I have guess on her family but am unsure of its accuracy. Matthew was a veteran of the Revolutionary War. I have not been able to find his parents.

   The second line is much farther back. Ann Brown's husband , Benjamin' s parents were Daniel and Sitha Walker Goble. Sitha's paternal grandmother was Sytha Brown daughter of Joshua and Alice Lunsford Brown. There is a record of their marriage in the Overwharton Parish books in Stafford County Virginia in July 1754. I can't find either Joshua or Alice's parents. 

  Any suggestions? Does anyone else have this lineage?
