KayeLT on Family Tree Circles

Hello all .. I am brand new here so im hoping i am doing this right .. I am currently researching the Cox (Cocks) side of my family and through information know that Thomas Cox lived in i think it was Buckley Street Essendon and "family folklore" says that he was related to WS Cox of the famous horse race ??? .. i would love to be able to prove or disprove this and any help or guidance would be so greatly appreciated.. thank you all
