Fisher/Stewar(t) or (d)

[smithy]

I have recently discovered that my Lyme Regis merchants who ended up in Ostende, Belgium married a Londer Charlotte Fisher. From her death certificate of 1837 in Belgium it states she was born 1794 to a Robert Fisher and Martha Stewart/Steward of London. Looked on IGI for any leads but no luck. By this time Robert Fisher has died.

Has any one got any Fisher's or Stewarts that may relate to this family.

Thanks

Sarah
