As an update to this.
I found that the family both Harris and Rycroft all moved to Walworth in the early 1830's.
Henry Harris died on Camden Street in 1832.
His daughter Sarah Harris married Edward Wynne a compositor there.
William Rycroft also died on Camden Street in 1838. I am awaiting his death certificate.
His father Richard Rycroft had died on Belgrave St in 1836 (couple of streets away).
They are both buried in St Peter Walworth.
Interestingly William Rycroft was a Print Colourer/Artist. And I discovered that there were a good number of other print colourers living in Trafalgar street and the surrounding streets. In fact when William Rycroft died his wife Susan also moved to Trafalgar street.
Gabriel Bayfield lived at 9 Trafalgar Street (in fact opposite to where Susan moved to) at that time. He was a famous print colourist and had a large team working from him largely from home. Sometimes whole families were involved - they did the hand coloured prints for Gould and later Darwin"s prints from the Beagle.
I have tracked down about twenty families living around those streets who are registered as print colourers. Often on baptism records and on the census they also refer to themselves as Artists (as Bayfield does himself). When you look at the prints you can see why - they really are beautiful.
In case anyone is interested the other names are: William Webb and all his children, Henry Foley, James Ayton, Joseph Cleere, William Matthew Hart and son William Matthew Hart, William and James Garrad, Charles Chittey and son Charles William Chittey, William Rycroft, John Triptree, Gabriel Bayfield and children Gabriel - later an Independent minister, Thomas - later an independent minister, Mary ann and Maria,
There are also lots of compositors and copper plate printers on these streets.
One of the Compositors is Edward Wynne brother in law to William Rycroft - he lives on Portland street and George street very close to Bayfield.
Thanks all
