We see Edwin with his first wife and family in 1871 living at Blockham, Worcestershire:
Edwin Tulk Head 31 Green Grocer Penridge Staffordshire
Mary M Tulk Wife 27 Worcester
Sarah A Tulk 6 Sipsom(?) Staffs
Francis J Tulk 9 mnths St Georges Worcester
__________

Edwin married Mary Ann Maloney in 1880.
__________

Edwin can be seen in 1881 living with his second wife, his three young children from a previous marriage, a new baby of their own, his wife's sister Ellen and his wife's father, at 11 Bolton Road, Aston, Birmingham, Warwickshire:
Edwin Tulk Head Mar 36 Porter Bham Warwick
Mary Ann Tulk Wife Mar 29 Dudley Stafford
Charles Tulk Son 11 Scholar Worcester Worcester
Edwin Tulk Son 5 Scholar Aston Warwick
William Tulk 4m Bham Warwick
John Maloney Wifes Father Wid 55 Shoemaker Clare Co. Ireland
Ellen Maloney Wifes Sister UnM 25 Pinworker Bilston Stafford

There's no sign of Joseph Knibbs, Mary Ann's son from her first marriage to Charles Knibbs so I believe it was him who died during q4/1878 at West Bromwich District, Warwickshire, England. He would have been just 3 years old in 1881.
__________

In 1911, Edwin was living at 5 Bordesley Green Road, Aston, Birmingham, Warwickshire:
Edwin Tuld Head 72 Marrtied Metal Mixer Penbridge Staffordshire
Mary Ann Tulk 61 Married (31 years) Dudley Staffordshire
William Tulk Son 30 Married Engine Fitter Birmingham Warwickshire
Laura Tulk Daughter in Law 30 Married (8 years) Core Maker Birmingham Warwickshire
Thomas Tulk Son 21 Single ????? Worker Birmingham Warwickshire
Ernest Prolly Grandson 8 School Birmingham Warwickshire

The census shows that Mary and Edwin had 5 children, all still living in 1911.
___________

It may well be this Edwin Tulk who dies in Aston, Warwickshire in q1/1922, aged 80 years.

Mary was the daughter of John Withey and his wife Eliza.
__________

Tulk wasn't a common name so I am reasonably sure iI have the right death date for Mary. She died aged 32 years so approximateky the right age to have been Edwin's wife.

Frank can be seen in 1901 working as a Brass Presser and living at Balsall Heath, Birmingham, Warwickshire.
__________

I think Francis married a girl named Louvain Rees during q4/1934 in the Cardiff District. Her death was recorded during q4/1939 in the Llanelly District of Glamorganshire, Wales. As Francis was listed as a widower in the 1939 Register, she will have died sometime towards the end of Q3/1939.
Louvain was born in the Llanelly District during q4/1914, so I preume she and Francis lived there after they married.
__________

We see Francis in 1939 living at 115 Larches Street, Birmingham, Warwickshire:
Francis J Tulk 15 Jun 1870 Brass Dresser Widowed
