Help to ID artist of a very well done miniature Madonna painting

Need the forums help

I hope to ID this artist. I can not read the signature. I know many miniature paintings
are by unknown artists, but this one are in a very nice quality so think there are
a chance it could be by a listed artist.

Thanks
Nicolai

 

The last four letters of the name look like "pold" but I can't tell the rest.

 

Pru?vold? Ringvold?

 

Don't think this helps either..............

 

Aquitaine, to me, that makes it look like RinGvold, which actually could be a name....

 

She's lovely. It's so hard to read but maybe Svold? Svoloi, Voloi?

 

Thanks forum for your kind help, and Aquitaine for the Photoshop, to make the
signature more sharp. I will let the forum know if I solve it, and ID the artist.
Thanks Nicolai
