Gibbie a Okrabister
Appellation names are proper names that describe a place of origin, such as Anne of Greengables. In StE these kinds of names are constructed with "of", sometimes shortened to o' (as in John o' Groats). In Shaetlan, however, appellation names are formed with a 'on', such as Gibbie a Okrabister. This parallels one of the Old Norse ways of forming appellation names, with á 'on' as in Atli á Gaulum 'Atli of Gaulum' [lit. Atli on Gaulum], which can still be found as one of the options for such names in the modern Scandinavian languages (as in Anne på Grönkulla, lit. Anne on Greengables).
Sometimes Shaetlan appellation names are "corrected" or altered to read 'of' (*Gibbie o Okrabister or even *Gibbie of Okrabister), but this is a hypercorrection based on the StE system. In fact the Shaetlan names were always formed with a 'on' and as such are a remnant of Norn naming practices that have been hiding in plain sight.
