Joseph Campbell 1847, son of Hugh Campbell, husband of Annie Pillar - Dromore c1900-1917

My great great grandfather, Joseph Campbell was born c1847, his father Hugh Campbell was a miller around Dromore. Joseph married Annie Pillar (daughter of James Pillar, a weaver) in the parish of Aghaderg in 1878, their residence together was initially Legannany in Loughbrickland where their son was born a year later. By 1905 Joseph is living in Mount Street Dromore, Annie has presumably died (however no death certificate has ever been found). Joseph married a second wife, Mary Jane Hodgen in 1908 and both are living - together with a step-daughter - in Weir's row Dromore by the time of the 1911 census. Joseph eventually ended his days in 1917 in Dromore. Would really appreciate any leads on the Campbells or the Pillars, as I hit the wall (20!) years ago!

Thanks!
