Who is the narrator in "A Modest Proposal"?

The narrator appears to be an Irishman, as he says in the final paragraph, "I profess, in the sincerity of my heart, that I have not the least personal interest in endeavoring to promote this necessary work, having no other motive than the public good of my country [...]."  He claims that his youngest child is nine years old, and his wife is past childbearing age, so he stands to gain nothing from this proposal;...

The narrator appears to be an Irishman, as he says in the final paragraph, "I profess, in the sincerity of my heart, that I have not the least personal interest in endeavoring to promote this necessary work, having no other motive than the public good of my country [...]."  He claims that his youngest child is nine years old, and his wife is past childbearing age, so he stands to gain nothing from this proposal; this must mean he's Irish since he's implying that he would otherwise be able to make a profit from his scheme (if his wife were still young enough to have babies).  Further, he calls Ireland "my country." 

Moreover, the narrator has evidently been attempting to cultivate a solution to the problem of Ireland's poverty and overpopulation for some time.  He says, "having turned my thoughts for many years upon this important subject, and maturely weighed the several schemes of other projectors," he has found all of them wanting in some respect.  The narrator seems to feel that it is his duty or responsibility to come up with and share an idea that will aid his country.

This seems to be all we really know about the narrator for sure, aside from the fact that the narrator is not Jonathan Swift.  Swift does not actually want the Irish to sell their babies to the English as a food source; he is using this proposal as a way to satirize the way in which English landowners seem to be figuratively devouring the Irish and Ireland.  If the English are willing to figuratively eat up the country of Ireland, then why not literally eat the Irish?  Swift pushes the reality to an awful extreme to show just how awful the reality really is.
