This may sound slightly unusual, and a long shot, but an appeal to our national sporting icon Conor McGregor may be something worth considering?
I say that, as he has in the past been particularly generous (to the tune of thousands) to people he doesn't know, has never met, but have fallen on hard times (including cancer patients, covering the cost of their treatment, amongst other acts of benevolent generosity).
Best way to make contact is via twitter:

Where he's active. I'd imagine a direct message would be most suitable (though a verified account is necessary to send DM's now).
I would emphasize your ties to Ireland of course.
If you present with and word your appeal as well, and with as much appreciation, as you've done here, I'd be surprised if you didn't get a response of some kind.
