Would the Jean Manson who married Hugh Ross be any relation to the Alexander Manson, M.D. of Thurso? He married Jane/Jennie Sinclair on 23 April 1799 and their daughter Marion Macbeth Manson (1800-1886) married Alexander Falconer Clarke JP, DL, (1802-1877), brother of my 2xgtgrandfather David Ross Clarke, the first one in the family to have 'Ross' as a middle name.
