Hay Jamie.
Looked up my name on Google and have ended up here. There's not a great deal of brech's in AUS. My father came to Oz from the UK around 1964~65. As far as i know his side of the name has a scattered past; UK, Scottland, Irland.
Interesting to know there are more Brech's out there!
Kind regards,
Jamie brech, Astralia.
