Kreutznaer — the German pronounciation would be ‘Kroitzner’ and the ending -naer or -när (instead of -ner) would add an unusual spelling to the rare name. The North German name ‘Kruse’ would be the far better candidate for the original family name. ‘Kreutznaer’ has on the other hand “Kreutz”, German for cross, in it which aroused a long discussion of the name’s potential emblematic value. Crusoe’s age of 87, his obscure northern origin and the apparent mispronounciation of the original family name could in any case hardly dispell doubts about his authenticity.
