That Ancestry tree links to an 1827 trade directory page for Amble (but appears to include the surrounding district?). It shows Mark Douglas Claxton's great grandfather Mark Douglas, gardener, Amble.
Worth a
look but it's familiar as it mentions the mystery paved path down to the Coquet. Toll collector's path? - previously discussed?
It also mentions a 'large' quantity of human bones deposited in a layer of thin red clay, found near the High Street ruins.
