Searching for Gg Robert Mcdougall

Hi All
I am searching for my Maternal GG Robert Mcdougall B. Troqueer Scotland 20/10/1873 Emmigrated to New Zealand around 1911, he is last shown on the 1911 census Scotland. I believe he left that same year. His parents were James(1842 - 1926) and Agnes Mcdougall nee Rutherford (1844-1916)both of Kirkcudbrightshire Scotland. Any help would be apprieciated. Ihave found a Robert (MAC)dougall in Pahiatua New Zealand who could possibly be him and am currently chasing this up. Thank you Angi
