Freda is a family name for me, so I'm biased here. But Freadda looks atrocious to my eyes. I suppose it could be a completely different name than
Freda and I just don't know enough about it. But without any information I have to assume this is a creative spelling. Yucko.
If you can give me more information, then I'll be happy to reasses. Did you ask your trainer about his / her name? How is it pronounced? Thanks.
