Gulliver,
So you've changed your name from Shiamsa (which sounds like 'sham' with a feminine ending) to a masculine sounding Gulliver, but you didn't in fact say that you're not female ...
'to gull' means 'to deceive' (as in 'gullible'), therefore Gulliver may mean 'bringer of deception'. Could this be a deliberate choice?
