Kirjassa "The Well Spring of the Goths" Ingmar Nordgren on tutkinut renkaisiin liittyviä paikannimiä Skandinaviassa ja muualla Euroopassa. Tein itse haun Renk-alkuisista paikannimistä tällaisin tuloksin:

Euran lähellä näkyy olevan Renkaanmaa, Turun lähellä Renko ja Hämeenlinnan ympärillä sekä E-Pohjanmaalla näyttää olevan ryppäät Renko-, Renka- ja Renkku-alkuisia nimiä. Ainakin noilta seuduilta on myös rautakautisia löytöjä. Lisäksi Lounais-Suomen rengasmiekkalöydöt näyttäisivät osuvan suunnilleen samoille seuduille:

The Nordic Ring-names
Because rings of all kinds seem to be so important for the Gauts, the Gutar and the Jutes in Scandinavia as well as among the Continental Goths, I asked myself when the ring acquired this significance for the Gothic peoples. Did it start on the Continent and spread up to the North or, on the contrary, did its symbolism originate in the North, and spread southwards? In trying to find an answer to this question I noticed an interesting factor in the toponymic geography of the Scandinavian region. There are numerous placenames and incolent names, i.e. nature names, beginning with the syllable Ring-, e.g. Ringsholmen, Ringholmen, Ringsbacken, Ringsåsen, sometimes with a Spjuttorp close by. The first two names mean Ring-island, and followed by Ring-hill, Ringridge and Spear-thorpe. It should be noted that the spear of Gungnir was regarded
as Óðinns.
Using maps and etymological literature, including the series Danmarks stednavn and Ryghs Norske gaardsnavne, I have endeavoured to comb Denmark, Norway and Sweden for Ring-names. Finland was not really a part of the Scandinavian area at this time and so I have included Finland in the Continental area. So far I have found 412 names in these three countries. Outside Scandinavia I first found another four in Brandenburgwhere both Goths and Burgundians stayed. One of these is called Ringenhain, the cult-place of the ring which is also the case in e.g. an Bohemian site. It is noteworthy that these places in Brandenburg are at the farthest eastern edge, within the Gothic area. There are Ring- names in other countries, however. In Poland, the starting point for the Gothic migration to the Pontic basin, there are quite a number. They indicate settlements such as farms and villages. The Slavicized names in Poland are constructed from a form ryn-, which appears also in the derivative rynek. The word rynek means ring and in Polish it has acquired the meaning market-place, square. According to Professor Salamon of Kraków it originates from certain Germanic dialects.(Pers.com) Brückner (1957: 472), Grimm (1893, vol. 14: 993f.), Mikloi (1886: 286) and Vasmer (19501958, vol. III) recount that this meaning has spread to Bohemia, Hungary, Silesia and Russia (cf. Rus. rynok, market). Cult and market in ancient times were closely interconnected, as is shown by e.g. the Disting in Uppsala. The Slavic names are of the same character
as the Nordic ones. In neighbouring countries there are still more. In Lithuania, also, there is a considerable number consisting mostly of settlements and a few names of rivers and lakes. Estonia has two, Livonia one and Latvia have three names.
