Campbell and his wife Martha Cruse are buried in the Wallin Cem. (Walker Co. #51)... they are listed as Gamel & Martha, but the dates are correct so I'm sure it's them... it is the family cememtery. My ancestors are buried there, and we knew them as Waldens. My great-grandfather left a list of family members who are buried there, but that was before Campbell & Martha died I believe... or at least MY part of the family had moved away by then. I can get you some info on the family, but I don't have anything on Campbell & Martha because they branch off... I have info prior to them, however. Go to Ancestry.com website & type in Campbell Walden or Wallen... I believe I have entered information already. The same families (Wallin/Walden/Hise are also in the 1850 Walker Co. Census records).
