Hi Again Barry,I have done a bit More Checking.But At the Moment Mostly Theory

If My Theory is Right,We start Of with Joseph Born abt 1742 ,No spouse Given His Son Joseph Born On 22 Aug 1762 In Burnley He Married Aged 16 .He Married About 1778,Had a Son Called Joseph Born 1778.It was This Joseph Who Married Ellen Greystick.
Dont Forget In those Days it was Legal To Marry At 15.
