It appears to have been a commerial shipping port in the late 1800's.
Specifically I'm researching a cargo ship voyage in 1893 from Miriuchi to
Clyde (Port Clyde, Maine, USA?) passing by the North Ireland coast with
timber lathes as cargo.

Today's Internet search engines don't find anything. (Apparently, there are
limits to Google and its siblings.)

Are there other newsgroups or website that might be familar with old city
names?

Thanks,
