On the Alcis’ Original Area of Worship: The Alcis were a pair of twin gods worshiped by the Naharvali, a tribe that is a subset of the Germanic Lugii peoples.
Tacitus’ Comments on the Worship of The Alcis: While Tacitus did note that he thought the Alcis were gods indigenous to the Naharvali, he also saw them as being analogous to the Roman gods Castor and Pollux. Tacitus also stated in Germania that their worship took place in a sacred grove and was presided over by a priest wearing women’s clothing.
On the Commonness of Divine Twins in World Mythology: The Alcis are far from unique in the sense that there are many sets of divine twins in folklore all over the world. These sets of twins include, but are not limited to, entities such as the Hindu Ashwini Kumaras and the Nara-Narayana, also from Hindu lore; Hengist and Horsa from the lore of the Angles, Saxons, and Jutes; and Ašvieniai of Lithuanian folklore.
On the Etymology of “Alcis”: At this point in time it would be a bold-faced lie for anyone to say that they knew for sure what the etymology of “Alcis” is. With the dearth of information and the obscurity surrounding them, it is currently impossible to say for certain that it’s derived from one word or another, though there are different theories that can be argued. It could be related to “alx,” having to do with sacred groves; it could be related to the Proto-Germanic “algiz,” the Proto-Indo-European “alk,” or the Latin “alces,” all having to do with elk; or it could mean “strength,” “safeguard,” or “I defend,” as suggested by J. S. Stallybrass. Regarding this last theory, which I find to be the most believable of the bunch, a relevant passage appears, as follows, in Stallybrass’ translation of (the beginning of chapter IV. of) Teutonic Mythology (Deutsche Mythologie) by Jacob Grimm:
‘Possibly [alhs] appears even earlier ; namely in Tacitus, Germ. 43 : apud Naharvalos antiquae religionis lucus ostenditur ; praesidet sacerdos muliebri ornatu, sed deos interpretation romana Castorem Pollucemque memorant. Ea vis numini, nomen Alcis ; nulla simulacra, nullum peregrinae superstitionis vestigium. Ut fratres tamen, ut juvenes venerantur.—This alcis is either itself the nom., or a gen.[] of alx (as falcis of falx), which perfectly corresponds to the Gothic alhs. A pair of heroic brothers was worshipped, without any statues, in a sacred grove ; the name can hardly be ascribed to them [here there is a footnote with the following text: ‘Unless it were dat. pl. of alcus [or alca άλκή[]]. A Wendicholz, Bohem. holec, which has been adduced, is not to the point, for it means strictly a bald naked wretch, a beggar boy, Pol. golec, Russ. gholiak. Besides, the Naharvali and the other Lygian nations can scarcely have been Slavs.’], it is the abode of the divinity that is called alx. Numen is here the sacred wood, or even some notable tree in it.’
On the Possible Roles of The Alcis: The Dictionary of Greek and Roman Biography and Mythology lists “Alcis” as being an epithet of Athena’s in Macedonia which meant “the Strong,” and Tacitus equated The Alcis with The Dioscuri (Castor and Pollux). The most obvious similarity between Athene and the Dioscuri is that they were all beings whose most pronounced traits included them being war gods, and so it seems reasonable to assume that “Strong” would have been considered an apt descriptor for all three of them even if it was never applied as an epithet to the Dioscuri. A footnote in J. S. Stallybrass’ translation of Grimm’s Teutonic Mythology (see above) states that he (Stallybrass) is not convinced that “Alcis” refers to a sacred grove and seems to be leaning more towards the conclusion that “Alcis” meant “strength,” “safeguard,” and “I defend” (or that the word was related to “alces”/elks, though I don’t agree with this theory). If a substantial connection (beyond Tacitus’ claims that they are similar but not stemming from the same source) between the Alcis and the Dioscuri exists, it might link the Alcis to the role of providing protection during war and therefore also support Stallybrass’ translation.

 I am not versed in any dialect of Greek, ancient or modern, so you should absolutely not take my word for it, but I’m reasonably sure that “άλκή” can be translated as “álkí.”
