Sanderson Family Thornaby On Tees

A Memory of Thornaby-on-Tees.

My grandfather was Tom Sanderson born 1859 in Thornaby on Tees.His parents were James Sanderson and Ellen Dunning.
Tom had a barber shop in Bridge Street and later in Lyndhurst street. He married twice and had several children.His first wife was Mary Jane Stoker who died in 1894.They had 3 children Ellen Cecilia , Isabel Mabel and Joseph Sanderson.
His second marriage was in 1900 to Elizabeth Ann Findlay ( nee Angus.)
Have no information on these families and would like to find out more about them and my father's early life in Thornaby.
My father was known as James Ernest Sanderson or Ernie. He was 2 years old when his mother Elizabeth Findlay ( nee Angus) married Tom in 1900. Children were John born 1900 Winifred 1904 Marjorie 1906 Beatrice 1907 Olive 1911.Any information on these families would be very welcome and would help fill in all the blank spaces in my family tree.
Many thanks
Shirley Meissner (nee Sanderson )
