my GG Grandfather was Peter Martin Deuchar born 17 Jan 1820 (from his own family bible), On his death certificate his parents were named as Robert Deuchar and Ann Johnman , ( over many years I tried to trace his birth record and his parents marriage record to no avail) BUT connecting with others on this site uncovered Peter registered his uncle James Johnman's death in dunning - further assistance from members Jeff Coleman and Andy Bernard (any relation to you ?) also uncovered your GGG Grandfather Robert Dewar previously Deuchar , both Jeff and Andy kindly sent me info and version of events & history - armed with this info I started researching under Dewar and found the following dunning parish record - Dewar Peter Martin lawful son of William Dewar weaver in Dunning and May Johnman his spouse born 17th January curt and baptized on 23rd January 1820. Way too much of a coincidence. I think I have the information on my old PC so I will try and find it. Do you have any other details or photos ? of the Deuchar/Dewar families. My own thoughts on the Dewar/Deuchar name is just down to the person who wrote the records possibly from DEQUHAR , DEWQUHAR etc.
