jodie55 on Family Tree Circles

Hi i am fairly new at this, so if i have done something wrong then dont hesitate to say. I am looking to trace my dads side of the family back to see if we have a connection to aboriginals anywhere.and im sure they are in mums side as well (johnson, henricks, brooks) I am pretty sure that we do and im not sure exactly how to find them.
If you can be of any assistance then i will greatly appreciate it.
Thanks in advance
