Roy,
I am a Kerruish in Australia trying to find my family my gr-grandfather was John William Kerruish a stonemason born in 1852 on IOM but moved to Lacashire. His father was John Kerruish a Mariner. They arrived in Australia in 1883. I would love to seewhat information you have about your family. If there is no connection just out of curiosity because of the name in common.
Cheers
