I don't know about your Campbells, but I know a bit about this line of Alexanders. The James you mentioned was actually a son of AA and his second wife, Margaret Jane McClure. James was b. Augusta Cty., Va. in 1766. He m. Martha Telford (or Tedford) in Va. Thereafter, they moved to Ky. (possibly Shelby Cty.). About 1821, they moved to Lincoln Cty., Mo. where James died in 1849. There are many "Archibald"s and "James"s in various Alexander lines. But this particular AA is my gggg-granddad, and I'mpretty sure of the data. Hope this helps a bit.
