Hi Maggie, Thank you so much for your reply. I have been in touch with another descendant of Margaret and I'll make sure I connect her with you. Not right now, I'm on my way to work. I have been unsuccessful with locating Richard Bruce or his family in Scotland. The family names which have been passed down are Parkinson and Hamilton which show as middle names for many of the descendants of Richard and his wife Maria (nee Parkinson also born Scotland) in Australia.
I have several images of Elizabeth Bruce, sister to Margaret.
