The only advice I can give, is that Penhalluriack seems to have been a change of spelling after the Penhalluricks settled in Australia. If you are interested to find out more Sharon Penhallurick might be able to help you, her website is www.penhallurick.co.uk Also, there is a person named Frank Penhalluriack who has been in touch with my family previously, ie about 30 years ago when she lived in Melbourne. I don't know if this has been any help to you. Still tis interesting to find out everyones stories.. I hope your search is sucessful.
