After their death, Javanese monarchs in the past were often given names based on the place they died. For example, the Mataram king Amangkurat I is also known as "Seda-ing-Tegalwangi", roughly "He who died in Tegalwangi", because he died in that town. Another monarch, Seda-ing-Krapyak ("He who died in Krapyak") was even better known by his posthumous name, and history books rarely mentioned his while-alive name.
Is there an adjective to describe these names? It would be handy in sentences like this:
The Mataram king, known only by his [adjective name] name Seda-ing-Krapyak, started a war with ...
The closest I can think is the adjective "posthumous", which explains that the name is not his name while he was alive, but it doesn't quite convey that the name was derived from his place of death. I'm looking for a word that do. I'm open to neologism though I prefer established words.
