Hi Casalguidi,
You are right that was their ages in 1871, I am not too sure where their parents were born, but I believe the Wells family were from Margate, but I don't know when. I have no idea at all about the Burtenshaws, but the info I have from the other census suggests they were all in the Deptford area of London. Sorry I am such a dimwit, but all the family that could have helped are long dead, and they weren't into reminiscing much when they were alive!!
Thanks for your prompt reply too.
Cheers Celia
