My grandmother's biological father, Wilfred Hainsworth, he married to Annie Wharmby, had 8 children, oldest twin died when they was two years old. My grandma is 7th child.
Wilfred died when she was approximately two years old. Annie couldn't handle it, so all of children was given away. My grandma was adopted by other family. All of her siblings have passed away.
To my best estimation, my grandma was born 1931, so he might have died in 1933 but i cannot find any records for that.
