Looking for any records of my 4th great grandmother Mahala West

I am currently working on a family tree and have came across my 4th great grandmother whose name was Mahala West. Knowing I have some Native American DNA in my family I would assume maybe Mahala West may have been Native American. I have what states she was possibly born in, her birthdate, death date, and place where she died. I also have who she was married too. All I know of her parents are that they both lived in Maryland, and Mahala may or may have not been born in either Pennsylvania, or Maryland. I do know she died in Pennsylvania. So my question is where could I go in hopes of finding out more information on Mahala too see if she indeed is Native American? I'm hoping I can dive deeper into my search of seeing who our Native American DNA comes from and learning more about that.
