Fun!
I've never been to Wales but I saw a T.V. program about how well they have been able to keep up their native language. That's quite an achievment in the modern, media soaked world. So, so cool.
Which brings me to Lwsi / Liwsi. Clever people that they (you?) are, how is Lwsi / Liwsi pronounced (as closely as you can in English)? Is it their version of
Lucy? Is it feminine or masculine?
Osian
Llyr is terrific.
Nel Grug? Is that an unusual name, even in Wales? Is Nel like
Nell in English, and is it a girl's name?
