Seònaid

Pronounced as /ˈʃɔː.natʲ/
https://en.wiktionary.org/wiki/Seònaid [noted -ed]

I was at school in South Africa, with a girl named Seonaid. She pronounced it like Shona, but once she remarked that it should correctly be SHOnid, with the -d sounded. It was, she said, "the Gaelic form of Janet", but in her family the -d was silent because that was easier for other people. I have no idea how accurate this might be.

I know someone with this name who pronounces it sho-NA.
