James Thomas Hancock b.1735 d. 1773 & Ann Smith, Maryland

Looking for information on James Thomas Hancock born 1735 and died June 18, 1773 of Port Tobacco, Maryland and his wife Ann Smith, born 1735 died 1762.

I cannot find any information on either of their parents or siblings. I have found a reference of a James & Ann Hancock and son William in the 1762 Baptism records of Warwickshire, England. But am not sure if this is really them.

Thank you
