Meaning and background
The story behind Jilly
Jilly is an affectionate short form of Jill in Behind the Name. The linked Jill entry identifies it in turn as a short form of Gillian, so the nickname has a documented personal-name chain behind it. Its -y ending belongs to that familiar diminutive form rather than supplying an independent meaning. An owner can use Jilly to honour a Jill or Gillian while keeping the intended connection explicit.
