Catherine Patterson died 26 August 1877, St Andrew, Dundee.
Her parents were given as James Soutar, shoemaker, journeyman, deceased and Margaret, m.s. Ewing, deceased.
Her son, Alexander, was the informant.
John is listed as seaman (M.S) - I presume 'merchant service'
Still no where near finding John but it's a start
