Campbells of Watten and Wick - Donald Campbell b1810

I have been researching my Campbell family tree and have traced it back it as far as Donald Campbell (1810-1885), born in Wick. He married Ann Ross (1809-)

Donald's son James Campbell (1849-1911) was born in Wick, Caithness and married Elizabeth Donn (1850-)

James' son Donald Campbell (1878-1970), my great grandfather, was born Canisbay, Caithness, Scotland and married Margaret Cunningham (1878 - ), he moved to Leith

Donald's son William Campbell (1905-1968), my grandfather, migrated to Australia in 1927

I am visiting the region around Wick 24 Sep to 27 Sep 2018 with my family and would like meet any relatives and get some more information about my ancestors.
