Hmm ... as an Ashkenazi myself (and one born in Israel), hopefully I may chime in.
Firstly, the word "Cohen" (in Hebrew) is pronounced with an emphasis on the syllable "hen" - i.e. Co-HEN. Yes, in English it's the other way, but many English-speakers (especially Aussies) are lazy about pronunciation of foreign words.
"Ashkenazi", similarly, is pronounced "Ash-keh-na-ZI". The "z" sound is like the word "buzz", and definitely NOT like "Nazi". (Someone once asked me that, and I had to explain very patiently that no, the two words are completely unrelated. From wiki:
"Ashkenaz" is a very old name ... mentioned in the Biblical book of Jeremiah ... and roughly equivalent to the kingdom of Phrygia (i.e. on the western borders of today's Turkey -Ed.)
...Later, it became associated with the Slavic territories, and later still (from the 11th century onwards) with northern Europe and Germany. The region of Ashkenaz was centred on the Rhineland and the Palatinate (notably Worms and Speyer), in what is now the westernmost part of Germany. Its geographic extent included northern France, and coincided with Charlemagne's kingdom.
However, just how the name of Ashkenaz came to be associated in the rabbinic literature with the Rhineland is a subject of speculation.
There!

Now you know more than you ever wanted to about the Ashkenazi Jews).
As for the Sepharadic Jews -- the kingdom of Spain, in Biblical Hebrew, is called
Sepharad (from Obadaiah 1:20). I've made notes in italics:
And the captivity of this host of the children of Israel, that are among the Canaanites (i.e. Bohemia), even unto Tzarfat (i.e. France), and the captivity of Jerusalem, that is in Sepharad (i.e. Spain), shall possess the cities of the Negev (i.e. the Negev desert, between today's Israel and Egypt -Ed.)
Even in today's Hebrew, "Tzarfat" and "Spharad" (note the missing "e") are France and Spain. (Germany is simply "Germania". Don't ask me why the Bohemians were called "Canaanites" -- I don't know!)
There are also "Teimanic" Jews (i.e. from Teiman, i.e. Yemen). In English they are known as Yemenite or Yemeni Jews, or Teimanim. They have their own cultures, foods, music and so on -- but very few remain in Yemen or other Arab countries, for they face discrimination almost daily.

Most of them migrated to Israel in the early 1950s, or to the UK or USA. And the
obligatory wiki-article can tell you much more about them than you ever wanted to know.[/url]
Having said that, some of my neighbours in Israel were Yemenite Jews -- some of the nicest and most hospitable people you could ever wish to meet.

They sometimes invited my family to Friday night dinners, and we reciprocated. I don't remember them much now -- it's been 30 years since my family left Israel -- but my parents still keep in touch with them.
