I have two questions about the Russian characteristic doll-set known as the Matryoshka:
1) I read that their name is derived from the girl name "Matriona", but does it mean anything specific? Also, does Matriona mean something?
2) I read that the smallest of the dolls (the one which contains nothing, and is homogenous and solid) is termed "the seed". Is that true? And if not, what is the more usual term for it?
Thanks in advance... The wiki article did not mention this info, and i may be needing it for a new short story
