I believe the answer is:
Here is my best explanation:
'henry' is the definition.
'from shanklin' is the subsidiary indication.
'from' says the answer is hidden in the clue.
'hank' can be found hidden inside 'shanklin'.
(Other definitions for hank that I've seen before include "Coil of wool for American Henry", "Loop of cord", "Skein (of wool, etc)", "-- Marvin, guitarist", "Henry - coil of rope, wool or yarn", "Skein (of wool, hair)", "Loop of yarn" and "A coil of wool for American Henry".)
