The signing of Dominic Drakes has caused me to wonder how many fathers and sons have played for Warwickshire.
I can think of the Smiths (Mike and Neil), the Maddys and, from further back, the Santalls and the Quaifes. I'm probably missing a few more so feel free to remind me!
In 1922, Willie Quaife and son Bernard played for Warwickshire at Derby while Billy Bestwick and son Robert represented the hosts.

The Doshi's & the Ibadulla's almost did

I should have remembered David and Jason Ratcliffe - I saw Jason only recently.
Also there were fathers and sons AJW Croom and Leslie Croom plus Charles and Fred Taylor.
I think that Jimmy and James Ord were grandfather and grandson.
Jason Ratcliffe may be the only example amongst all of them where the son was a better player than the father.
