Hi Suz,
Thanks for your response.
Yes, Homey is a bit of an anomaly, I had wondered if this was a spelling/transcription error as he doesn't appear in any later census but is listed as male so not sure about Naomi.
The information which I said was from the marriage banns is because it was listed as Kent marriages and banns so my mistake but the marriage certificate lists the witnesses to William and Elizabeth's marriage as
Joseph Dawson and Margaret Rossister
Daniel's occupation is listed as Hawker.
Yes my great grandparents were William Daniel Harris and Harriet Ann Baker and as I mentioned I have been told that the Harris side may have been showmen/fairground travellers but as I said I have no idea if any of that information is accurate. As you have found, looks like it was indeed the Rossiter side!
I will look a bit further and see what I can find.
Many thanks, much appreciated
