Well I haven't a clue what you are looking for in Ireland but you seem to be looking for a Robert in Glasmullagh so I found him on 1901 Census, C of I.. It seems you can't find him in 1911 or something so here are all the 'Fermanagh born' 'C of I' Weirs in ALL of Ireland in 1911 as I think that's what you are looking for in Ireland,,, I've read your post a few times trying to figure out what to search for. http://www.census.nationalarchives.ie/search/results.jsp?census_year=1911&surname=Weir&exact=&firstname=&county19011911=&county1821=&county1831=&county1841=&county1851=&townland=&ded=&age=&sex=&relationToHead=&religion=Church+of+Ireland&education=&occupation=&marriageStatus=&marriageYears=&childrenBorn=&childrenLiving=&birthplace=Fermanagh&language=&deafdumb=&search=Search&sort=firstnameSort&pageSize=100&houseNumber=&familiesNumber=&malesNumber=&femalesNumber=&maleServNumber=&femaleServNumber=&estChurchNumber=&romanCatNumber=&presbNumberDiv=&protNumber=&parish=&barony=&yearsMarried=&causeOfDeath=&yearOfDeath=&familyId=&ageInMonths=&pager.offset=100 might be something new for you DH
