According to Berta Lawrence in her ‘Somerset Legends’ (1973) during the civil war there was a man called Jan Swayne who lived in Moorlinch. Found to be a ‘rebel’ he was dragged from his bed to be taken to Bridgwater where he was to be hanged. Somehow he persuaded the troopers who came for him to untie him to show his crying children a last entertainment of how far he could leap (the ‘police’ are always stupid in films today too, so no change). Naturally he took three immense leaps – a hop, skip and a jump – which took him into the impenetrable and swampy Loxley Woods where he could hide safely.
The site of his leaps is known as ‘Swayne’s Jumps’ or ‘Swayne’s Leaps’ and you may find four (or even five) small stones in a line. The Somerset Historic Environment Record mentions them being in the SMR records, but I don’t see a mention on Magic. Perhaps they’re old, perhaps not? In the distant past perhaps this area would have been even boggier. Take your wellingtons and have a look. Apparently an old sign designates the place ‘Jan Swaynes Jumps’.
The folklore is similar to that attached to other pairs or lines of stones (eg the Deerleap Stones).
