Rulkoviuse

(Adolph Johann Rulcovius, 1796-1871)

Thus named (1885-1939, with various spellings, both c and k) after owner of underlying land who split it up (Wikipedia gives an unlikely date of 1878) to create the now Virmalise street network. The Latinised surname, Rulcovius, follows a practice widespread across Europe from the Middle Ages onwards of using a Latin form of one’s name in public, professional and learned life; KNAB and the street name use the Estonian spelling with k.
