The restricted government files, which are closed to the public because of their sensitive nature, span from 1886 and 1972, and include information on births, family history, relatives, and medical records.
Research experts from Aboriginal History Western Australia can help people access these historical records, and will be travelling across the state's southwest to host free family history sessions.

They'll travel, alongside the State Library of Western Australia's Storylines team, to Collie, Manjimup, Margaret River, Busselton, Bunbury and Eaton, helping families begin the journey of researching their family history.
The Storylines archive holds more than 12,000 photographs and other documents relating to Aboriginal people in the state.
Aboriginal History WA community education officer Duane Kelly said these sessions are a great starting point for Indigenous people to know and understand more about their history.
"It's critical that community knows about these records because it's people's family history, their personal ancestry and contains a lot of personal and sensitive information that can be life-changing for a lot of people to understand who they are a bit better, particularly people that might have been removed or impacted by various policies," the Nanda and Amangu man told AAP.
Mr Kelly said Aboriginal History WA, which is part of the Department of Local Government, Sport and Cultural Industries, also has a number of truth-telling projects, which will be highlighted at the family history sessions.
The truth-telling projects focus on institutions like missions and orphanages or other subjects like Aboriginal trackers, or the extent of Indigenous involvement in agricultural and pastoral leases in the state.
"The truth-telling projects are a way for us to highlight some of the lesser known aspects of WA's past relating to Aboriginal history as well as provide tools for families to do their own family history research," Mr Kelly said.
"The wider community, when they start to learn about more of these sort of topics, might have a greater understanding of what's happening within out community across the state and internationally as well and how these past policies have had a lasting impact on community today."
Family history sessions will be held in Collie on February 10, Manjimup and Margaret River on February 11, Busselton and Bunbury on February 12, and end in Eaton on February 13.
