Think of the phrase "home country" as having the same meaning as "Mother-/Father-land" -- that place from whence my people came. Many of Irish decent still refer to the Old Country" as if they had left County Kerry just last week while in fact it's been 4 or more generations since anyone from their line has been there. Same with other ethnics.
Not that I have seen a whole lot of it recently, but during the time the TV show "Roots" was airing there was a big push amongst the black community to define oneself as being from a line stretching back to this or that African country, or better yet to a specific tribe. The best part of the whole African origins thing I saw was a few years ago when an immigrant friend of mine married off his daughter - he is first-generation from Ivory Coast, and the groom was third-generation but could prove all the intervening marriages were not only between only folks from Ivory Coast but from a specific tribe, thus a "pure" blood line. It was important to them in the same way marrying another Catholic is important to Catholics. I wonder if in another 2 generations they will be able to still claim that purity.
I have no idea where Michelle is from, and I seriously doubt if she does, either. Barry has the chance to prove where he's from but has declined to do so.
stay safe.
