My contribution is to suggest that R G Halliburton, Q.C., from Canada, who spent time in St Elizabeth, Jamaica, in the 1880s, may be the origin of 'Allibutton'. He raised hackles among those in authority by insisting that they were not doing their job of assisting the poor in that parish. He did what was essentially pro bono work to help the poor in their struggles with the establishment. The phrase seems to have originated in the 1890s, so that would fit with the chronology of Haliburton's influence in Jamaica.
