Yes, it's Davy - in that version anyway! In the one I grew up with, which is near as dammit to Bob Cann's grandfather's (he claimed) there are 7 men plus Uncle Tom, not 6 + as in the 'Woolworths' version:

Tom Pearce, Tom Pearce, lend I the' gray mare
Right fol ol de rol, riddle I O
For I wants for to go to Widecombe Fair with
Bill Brewer, Jan Stewer, Harry Hopkin, Jimmy Davey,
Philly Wigpot, George Parsley, Dick Wilson, Tom Cobleigh and all. Yer it's Uncle Tom Cobleigh and all!
