Hi Alfie
I don't quite know where to start

The name Bert Cowley has started to ring a bell. I too found Bertram on the 1911 census married to Nellie with five children, living in Derby. He was 35 at the time.
Mr Hazlehurst kept the Queen's Arms in 1911.
Abner Cowley b. Winshill, Derbyshire, found lodging at 20, Horton Street, Derby, with a Joseph Edward Brown. Abner was a Locomotive fireman.
I also found a marriage for Abner in Derby in 1912. Brides maiden name was Keeling. He is down as being born in Winshill Derbyshire. So i took that to be him.
Now we come to the interesting bit. I actually received the marriage certificate on Friday, but I was going to wait until i had found when Bert Cowley took over the tenancy of the Queen's Arms by looking in the trade directory for Winshill in the local library.
Alfie....Bertram's first wife must have died. He married again in 1924.
Date; 17th May 1924.
Bertram Cowley. 49 years. Widower. Joiner. 15, Carrington Street, Derby.
Fathers name Ralph Cowley (deceased) Ralph was a sawyer.
Ellen Ruth Hickman. 35 years. widow of 15, Harrington Street, Derby. Her father was Richard Harrison, Coal Merchant.
Witnesses were Henry and Nelly Harvey.
Hope this helps. I will be going to the library on Thursday, so will know more then.
Regards
Molly
