Would you say the name variation is more common there than in non Latin places? You'd need to check the level of occurrence between them. Nonetheless it is common indeed.
I don't have all the data to claim that the use of the name Joseph is more common in Latin speaking countries than elsewhere, all I used was just a website to show that indeed it is very common. That is from what little I know of my own, of course a detailed research about the percentage and the time-frame of that specific name being in use in those countries would shed far more detailed information and a clear judgement on that.
But that was just a name, what about the name Mary? I know that name also has the corresponding of it in Hebrew as Myriam, but that in itself might mean a lot of things. Either it is a original Hebrew name that only them used and keep using it, or, it's just a name that a part of the Jewish population picked up and twisted a bit from the host country where were they living, prior to the foundation of Israel. It's very common for migrants to pick up and use language, customs, traditions and naming of new borns from the host country in order to blend in and form marriages, it's just human nature. We want to be accepted in different communities if we're a minority, especially if the staying has been in the time span of hundreds of years, it's just inevitable.
I'd expect from the top of my head the most common Hebrew names to be after the characters of the Old Testament, like the angels for example:
Abatur, Adathan, Aglibol, Ananiel, Anush, Arakiel, Arariel, Adriel, Ariel, Armaros, Artiya'il, Asbeel, Asmodel, Azazel, Azrael, Barachiel, Baraqiel, Batariel, Beburos, Bezaliel, Bihram Rabba, Camael, Cambiel, Cassiel;
Chamuel, Chazaqiel, Daniel, Dadrail, Dumah, Eleleth, Gabriel, Gadreel, Hadraniel, Hahasiah, Hanibal, Haniel, Harut, Hashmal, Hamalat al-Arsh, Hibil Ziwa, Hofniel, Imamiah, Ieshim, Israfil;
Jegudiel, Jehoel, Jequn, Jerahmeel, Jophiel, Kadkadael, Kalka'il, Kepharel, Kerubiel, Kiraman Katibin, Kokabiel, Kushiel, Lailah, Maalik, Macroprosopus, Malakbel ,Manda d-Hayyi, Marut, Mebahiah, Melek Taus, Metatron, Michael, Moroni, Mu’aqqibat, Munkar, Muriel;
Nakir, Nanael, Nathaniel, Netzach, Nidbai, Nithael, Nuriel, Ophaniel, Pahaliah, Penemue, Phanuel, Poyel,, Pravuil, Principalities, Ptahil, Puriel, Radueriel, Raguel, Ramiel, Raphael, Raziel, Rikbiel;
Sabriel, Sachiel, Sahaquiel, Sam Ziwa, Samael, Samyaza, Sandalphon, Sarathiel, Sariel, Saureil, Schemhampharae, Selaphiel Seraphiel, Shamnail, Shamsiel, Sheetil, Shilmai, Sidriel, Simat Hayyi;
Tamiel, Temeluchus, Tennin, Turail, Turiel, Uriel, Uziel, Vasiariah, Vehuel, Wormwood, Yadathan, Yarhibol, Yomiel, Yushamin, Zachariel, Zadkiel, Zagagel, Zaphkiel, Zaqiel, Zephaniel, Zephon.
And some of these names are widely used among the Hebrews and Christians also. But when someone goes into the New Testament characters that were supposed to be from the Levant we are faced with a completely different set of names that has little to do with the Hebrew language.
Let's look for example at the names of Jesus's prophets, they are:
Peter, Andrew, James, John, Philip, Bartholomew, Thomas Mathew, James, Jude, Simon and Judas Iscariot.
The name of Jesus is not used much as it is in it's form in Christian populations and I don't know why, maybe it's not meant to be a name, maybe it was considered heresy by the Catholic church to be used by peasants, but the name Christofor of Kristos or Chris or Kristaq etc are widely used and very common.
My point is that it makes sense for Christianity to have been born in the region of Spain, Portugal and France and being spread out from there judging from the perspective of people's names. Every religion has to start with the original names of people and then it self-fuels the spread and adoption of those names as it gains traction and a large growing follower base.
Here are some interesting maps of the spread of Jewish population throughout Europe in time.
Looking at these maps one would expect to see a lot of Hebrew names in accordance with the Old Testament characters in Eastern Europe like Ukraine, Poland, Baltic countries and Germany if they strictly maintained their national identity and didn't intermix with the other hosting population. Or maybe they did just that because in order to blend in which is a natural national assimilation process, and what are refereed to as common Hebrew names today are highly influenced by the local population of those countries.
It would be interesting to see the most wide spread names in Israel today and try to trace back their origin
Of course I'm not a scripture scholar and don't have all the data available to back up my thoughts admitting that I'm prone to make mistakes, because I've always followed my intuition about what's going on and try to rely less on sponsored study papers.
Some very interesting information regarding the Hebrew population for anyone wanting to delve more in because I'm going a lot off topic with the names used in Christian countries which is a very large topic in itself.
