I am trying to find a family for my 5x gr-grandmother Frances Keep born abt.1751/2 in either Berks. or Oxfordshire. I know that when she married John Bradstreet in Sutton Courtnay, Berks in 1778 ,William Keep ,her brother is named as bondsman. She then lived, raised her family and died in Oxford but I have so far been unable to find a baptism that fits. Does she fit into anyone elses tree?
