Mirella Script  Vorgeschlagen von Heron2001 

This is so similar to Mirella Script -
the commercial one - with all glyphs can be found here: https://creativemarket.com/Paulow/9756-Mirella-Script

for personal use it's on dafont...

NOT THE FONT - just a good substitute. With modification - it can be there!

Thanks for your help heron
