Hi - Back again,
This is all I know about the Booth gypsy connection...

Ann Cook bn 1806 - 1870 Gunthorpe Notts
One of their other daughters and Everett's sister was a Violetta Plumb bn 1833
who married in 1852 2Q Nottingham a William Caunt.  Someone has a lot of their family history on line.  They ended up living in Grantham.
Not sure if this helps you...
What I have learnt by reading books is that when looking for Gypsy relatives you have to forget how the non-gypsy folk use their names in a set way.  Travelling folk interchange the surname - use mothers maiden name, or an alias - and change their first name from time to time as well - also they didn't always marry in the way we would call marry - so there is no legal trace - it's wonderful!!!  But most often there is a christening somewhere - you just have to find it.
I really need to make the connection with the Smiths and Keziah Booth...
