Celtic Football Club was formally constituted at a meeting in [[Saint Mary's, Calton|St. Mary's church]] hall in East Rose Street (now Forbes Street), [[Calton, Glasgow]], by Irish [[Marist Brothers|Marist]] [[Brother Walfrid]]<ref>{{cite book |last=Coogan |first=Tim Pat |title=Wherever Green Is Worn: The Story of the Irish Diaspora |publisher=Palgrave Macmillan |year=2002 |page=250 |isbn=978-1-4039-6014-6}}</ref> on 6 November 1887, with the purpose of alleviating poverty in the East End of Glasgow by raising money for the charity Walfrid had instituted, the ''Poor Children's Dinner Table''.<ref>{{cite book |last=Wagg |first=Stephen |title=British football and social exclusion |publisher=Routledge |year=2002 |page=196 |isbn=978-0-7146-5217-7}}</ref> Walfrid's move to establish the club as a means of fund-raising was largely inspired by the example of [[Hibernian F.C.|Hibernian]], which was formed out of the immigrant Irish population a few years earlier in [[Edinburgh]].<ref>{{harvnb|Wilson|1988|pp=1–2}}</ref> Walfrid's own suggestion of the name ''Celtic'' (pronounced ''Seltik'') was intended to reflect the club's Irish and Scottish roots and was adopted at the same meeting.<ref>{{harvnb|Campbell|Woods|1987|p=23}}</ref><ref>{{harvnb|Wilson|1988|p=3}}</ref> The club has the official nickname, ''The Bhoys''. However, according to the Celtic press office, the newly established club was known to many as "the bold boys". A [[postcard]] from the early 20th century that pictured the team and read "The Bould Bhoys" is the first known example of the unique spelling. The extra ''h'' imitates the spelling system of [[Scottish Gaelic|Gaelic]], wherein the letter ''b''  is often accompanied by the letter ''h''.<ref>{{cite web|last=Thomas|first=Gareth|title=The Crest Dissected – Celtic FC|url=http://www.thefootballhistoryboys.com/2014/12/the-crest-dissected-celtic-fc.html?view=sidebar|website=The Football History Boys|date=5 December 2014 |access-date=26 August 2015|archive-date=4 September 2015|archive-url=https://web.archive.org/web/20150904075246/http://www.thefootballhistoryboys.com/2014/12/the-crest-dissected-celtic-fc.html?view=sidebar|url-status=live}}</ref>
