A noun changes the y to ies - countries,
With names the y remains a y.
So it would be Germanys.
She got two Grammys.
There are teo Billys in my class
Hmm... interesting.. I might agree about personal names e.g. two Marys, although I have seen Marys and Maries, and I am willing to concede two Grammys. However usage seems not to be fixed, and I assert that the "-ys after a vowel/-ies after a consonant" rule is within the bounds of acceptability. Especially when writing about Italy, it would seem! Below I submit some (not very scientific) evidence.
Google (using quotes to get exact match):

Example: Joseph Luzzi takes the title of his brief, bittersweet new book, “My Two Italies,” from Shelley, who, in a letter of 1818, distinguished between the Italy of “the green earth and transparent sea, and the mighty ruins” and the human reality he encountered there: “The one is the most sublime . . . the other is the most degraded, disgusting and odious.” (NY Times)

Example: ...the upshot was that he tried to organize the economic and social foundation for the Kulturkampf between the two Hungaries that existed in his mind (Political Transformation and Changing Identities in Central and Eastern Europe, edited by Andrew M. Blasko, Diana Januauskiene)
Also, "The two Hungaries" (spelled thus) is how historians refer to the two mediaeval Hungarian kingdoms united in 1102 AD under Coloman.
"two Picardys": 1 result
"two Picardies": 0 results
"two Lombardys": 5 results (mostly about Lombardy poplar trees)

Example: In many cities of the two Lombardies (as Riccoboni informs us) the spring of the year is allotted for comedies" (The Tragedies of Sophocles, from the Greek. Trans. Thomas Francklin)
So you see there is no simple rule for countries/locations.
