Hi,
I came across your thread whilst undertaking some family research.
I am the great niece of James William Blanchard.
He was born in Hull to Louisa Martha Blanchard and William Herbert Blanchard in 1922/1923. Siblings included Marjorie Blanchard, Lilian Blanchard, Percy Blanchard and Mary Blanchard (My grandmother). I am not aware James had any family. All his brothers and sisters are now deceased.
If I find anything further I will post this.
Thank you for your lovely thread. Kind regards
