Cage, thank you for the options.  Sounds disappointed but I'll try.  In my case the JCMs at Antonia's hip2 and thighs are the hardest.

As I know, one bone per group and the border of the groups can be shared by 2 groups only, one parent can have many children.  I wonder if the the bone can have any effect to the group of its siblings? 

odf, is it ok if I convert Antonia to work in Blender?
