Looking for Two Different Family Lines Mother S Side and Father S Side Lawns of Leeds England and Halls of Georgia

I am trying to find information with relation to my family. I know that Arsenio Hall was my father's first cousin. The last name is Hall and they were from Augusta Georgia originally. I would like to names of his brothers, parents, etc. My grandmother passed away and all I know is her married name, Lee Hall, she was also from Augusta Georgia.

My mother's side of the family last name of Lawn, my grandfather Melvyn Lawn came from Leeds England and eventually settled in Windsor, Ontario.

Any information with regards to either of these lines would be wonderful.
