John Fraser b1801 Sarah Margaret Sharpe

Hi

I am looking for any information on John Fraser b1801 and his wife Sarah Margaret Sharpe married in Islington London in 1831.  They had a son John Simon Fraser b1833 in Tower Hamlets.  They are believed to have originated from Scotland, maybe Midlothian.  John snr was possibly an engine driver and John jnr was an engine fitter.  John jnr married Mary Alice Jackson in Durham in 1850ish. 

After the marriage I lose all sight of John and Sarah.  A family story has John originating in Midlothian, in possibly the Newbattle or Peebleshire areas.

Any help please
