Using a PoD after the Acts of Union 1707, create a timeline in which France is, by 1900, part of the United Kingdom. Whether Ireland is or not, in whole or in part, is up to you. Likewise, other areas may or may not be part of the UK, so the name written in the title is not a requirement (though, for a somewhat unlikely example, 'the Holy and United Kingdom of Great Britain, France, Ireland, the Germanies, South Africa, and North America' is a bit of a mouthful).
