Disgaea was ported to the DS and is available in English, I should mention.
I've also heard the Luminous Arc series is a series of strategy RPGs for the DS; the first 2 have been released in English and the third may yet get an English release, because it was released in Japan half a year ago.
Also, for the Shining games I mentioned...
Feather has not yet been released in English, and I don't know whether it ever will be (it has been just over a year since its release in Japan, as the first strategy RPG in the Shining series in 12 years, and it didn't sell well even there)
The first Gaiden game and Final Conflict have not been released in English either, although Gaiden I became Book I of Shining Force CD (Gaiden II became Book II, and there are 2 other shorter Books); meanwhile Gaiden II was released in English as Shining Force II: The Sword of Hajya.
Only the first scenario of Shining Force III was ever released in English (there are 3 scenarios sold as separate discs and a bonus CD).
There is a working
translation for Final Conflict (although none for the first Gaiden that I know of), an active
translation project for the rest of Shining Force III, and widespread clamoring for a translation of Feather although little publicly visible progress, possibly waiting for Atlus or Sega itself to finally make its own translation; I'm putting my hopes on a translation becoming available by late 2011, considering how long it took for the Mother 3 Fan Translation to be finished.
As for Fire Emblem, the first 6 games and the Satellaview game were released only in Japan, but all of them have been translated, to varying degrees of success; I have linked to the translations where I could find them.
1
Fire Emblem: Ankoku Ryū to Hikari no Tsurugi (NES 1990, "Shadow Dragons and the Blade of Light", re-made for DS in 2008 as "Fire Emblem: Shadow Dragon", which was released in English)

Then there's Tactics Ogre: The Knight of Lodis (GBA 2001)
Finally, the Final Fantasy Tactics sub-series...

Final Fantasy Tactics Advance (GBA 2003)
Final Fantasy Tactics: The War of the Lions (PSP 2007)

While looking this stuff up I learned about yet another strategy RPG series that has never been released outside Japan: Black Matrix.
Black/Matrix (Saturn 1998, DC 1999, PSX 2000)
Black/Matrix II (PS2 2002)
Black Matrix Zero (GBA 2002, re-released as "Black/Matrix 00" for PSX in 2004)
This is the only translation of Black Matrix Zero I could find, and it only finished a few menus:
