My husband is descended from a Susan Ditch (born 1888) whose father we believe was Alfred Ditch (born approx 1863) and grandfather was Thomas Ditch (born approx 1826). This is based on Susan's age when married and then tracing back to the 1891 census. They lived in Chelsea.
Susan married George Prince from Wandsworth.
Would this tie up with any of your information? My husband and his family would be very interested if it did.
