What information do you already have about this family? What would you like to find out? If you haven't already checked the censuses, that would be a good place to begin. From a rapid search of the 1901 census transcript on Anc'try, they seem to have been at Calrossie, parish of Logie Easter, where Hugh was a ploughman (birthplace Kinlochbervie though it is horribly mangled in the transcription). There is a 40 year old Hugh Munro in the parish of Tain in the 1911 census index on ScotlandsPeople. I'd advise checking out both censuses on ScotlandsPeople (1911 is not available online elsewhere); the 1911 census would tell you if there were any other children, dead or alive, and also when the parents' married. Well worth paying to see the actual records. Hope this helps.
