Hey Hon,
For a start a big HUG.
Families and names - OMG, don't start me!!
Remember you are a living memory, so people recall the memory. They may accept you totally but their brains kick in the memory.
I reckon it takes the average family about 2 years to stop using you previous name. It helps if you change your name totally from your past one. So in your case go with Ella, and never even respond to Chris, Kris or Krys - or anything else.
