suzannem on Family Tree Circles

I am trying to contact relatives of my grandfather Howard Arthur Marks who was a solicitor in Manly, NSW, Australia.

He was one of 11 children. My father, Horace Norman Marks, formerly of Seaforth, NSW, Australia is in a nursing home with dementia. I believe his cousin Howard Marks, now deceased, wrote a family history and I would like to obtain a copy of it.

I would appreciate hearing from anyone who can assist me in this endeavour.
