Hello Justin,
Yes indeed, this is my ancestor and I have quite a lot of information on Elizabeth Parke.
At the moment I am looking after a 3 year old grand daughter and working at the same time. I am off to Tnga for a week next week, but if you can wait, I will sort out my info and let you know what there is.
You can email off this post at my first name with @clear.net.nz so that we can be more private.
Are you living in Australia?
Cheers
Raeanne
