Varro, writing in book 5 of De Lingua Latina, about how things are named in Latin (!), has many examples, though not exactly of the kind of sentence you're asking about. Here are a few.
Amnis id flumen quod circuit aliquod: nam ab ambitu amnis. Ab hoc qui circum Aternum habitant, Amiternini appellati.
An amnis is a river that goes around something; for amnis is named for ambitus, "circuit". From this, those who live around the Aternus are called Amiternini, "men of Amiternum".
Ubi nunc est Roma, Septimontium nominatum ab tot montibus quos postea urbs muris comprehendit; e quis Capitolinum dictum, quod hic, cum fundamenta foderentur aedis Iovis, caput humanum dicitur inventum. Hic mons ante Tarpeius dictus a virgine Vestale Tarpeia, quae ibi ab Sabinis necata armis et sepulta: cuius nominis monimentum relictum, quod etiam nunc eius rupes Tarpeium appellatur saxum.
Where Rome now is, was called the Septimontium from the number of hills that the city afterward embraced within its walls; of those, Capitoline got its name because here, it is said, when the foundations of the temple of Jupiter were being dug, a human head was found. The hill was previously called the Tarpeian, from the Vestal Virgin Tarpeia, who was killed there by the Sabines with their shields and buried; of her name a reminder is left, that even now its cliff is called the Tarpeian Rock.
Some of these are ambiguous, like Septimontium (which would be the same in the accusative, and isn't really following its participle), and not all are exactly what you asked for, such as appellatur, which the main verb rather than a participle. But I think these examples illustrate that the name is given in the case appropriate for its place in the sentence; the name is not put in the nominative to show you its canonical form.
Cum Caelio coniunctum Carinae et inter eas quem locum Caeriolensem appellatum apparet, quod primae regionis quartum sacrarium scriptum sic est:
Caeriolensis: quarticeps circa Minervium qua in Caelium montem
itur: in tabernola est.
Caeriolensis a Carinarum iunctu dictus…
Joined to the Caelian is the Carinae, "the Keels"; and between them is the place which is called Caeriolensis, obviously because the fourth shrine of the first region is thus written in the records:
Caeriolensis: fourth shrine, near the temple of Minerva, in the street
by which you go up the Caelian hill; it is in a booth.
Caeriolensis is so called from the joining of the Carinae with the Caelian.
Suburam Iunius scribit ab eo, quod fuerit sub antiqua urbe; cui testimonium potest esse, quod subest ei loco qui terreus murus vocatur. Sed ego a pago potius Succusano dictam puto Succusam: quod in nota etiam nunc scribitur SVC tertia littera C, non B. Pagus Succusanus, quod succurrit Carinis.
Junius writes that Subura is so named because it was at the foot of the old city (sub urbe), proof of which may be found in the fact that it is under that place which is called the earth wall. But I rather think that from the Succusan district it was called Succusa, for even now when abbreviated it is written SVC, with C and not B as third letter. The Succusan district is so named because it succurrit, "runs up to", the Carinae.
