Fuller
The spook names Fuller & Walker may be a pun of קצר qṣr for “fulling” something (by “walking” on it), with קצר qṣr for Castro meaning “palace”. It’s spelled the same! All those celebrities who are named Fuller, jobbed as a fuller, or had a fuller father, are really “palace”-born aristocratic parasites.

קצרה qṣrh : fort, castle; Latin castra (= fortified camp), (whence also Syriac קַסְטְרָא (= fortified place, fort, castle). Arabic qaṣr (= castle, palace) is borrowed from Hebrew קַצֽרָה Latin castrum originally meant ‘that which has been cut out’, from *kastrom (= a cutting tool), whence also Latin castrāre (= to cut, geld), which is probably cognate with Old Italian śásati, śásti (= cuts), śástram (= knife), Greek keazin (= to split). — Hebrew (Klein)
