The Clayton family appear on the electoral register for 1920 living at 20 Garbett Street, Ladywood . Registered to vote are William Henry Clayton (g-granddad), his wife Mary and a son Harold.
Just along the same court at 1 back of 17 Garbett Street is Frederick Clayton and his wife Emily Anne and another brother, George Samuel.
Also in the 1920 electoral register is Terence Millington at 1 back of 32 Garbett Street. So both of my father's grandfathers were living on Garbett Street in 1920.
Twenty years later we find Terence with his second wife Jane and two sons George and John (aka Jack) living at 75 Bishopsgate Street in Lee Bank.
