I know this is an old thread but anyone with an interest in the families of HERCULES and PETER STANLEY (from about 1710 to about 1910, from primarily Hampshire and Berkshire) may be interested to know that these are the latest family covered in the Romany and Traveller Family History Society's "Famous Families" series of books.
The RTFHS website shows the Surnames included in the trees as:
Alexander, Ayres, Barney, Blake, Bowers, Bellows, Broadway, Bullock, Bundy, Bushell, Cannon, Carter, Charman, Clark, Cleft, Colen, Collins, Cooper, Davis, Day, Drake, Evans, Fletcher, Gardner, Goble, Goddard, Griggs, Haynes, Hilden, Hooper, Hughes, Ivall, James, Jerrim, Lee, Light, Limburn, Martin, Messenger, Miller, Millis, Mills, Moore, Newman, Parker, Pearce, Perren, Pidgeley, Pike, Proudley, Puttick, Rogers, Rolph, Rook, Sands, Short, Smith, Spencer, Steer, Strange, Targett, Ware, Weeks, Welch, Westwood, Whale, White, Whittle, Wittel.
I hope this helps someone.
