Re: Ilett origin
The first Iletts, a very old seated name apparently, were found in Cambridgeshire and Suffolk. There was a Thomas Ilett in Foxton, Cambs. My own interest is in John Ilett, (1793), a calico priner and thought to be a Charterist, who came from South London. He was my G G G G Grandad!
WOndering if you too originate from London? Ancestry.com has a whole family tree of my Iletts, by the way!
The name has a lot of varients, from Ilott to Aylett etc. Happy hunting!
