Well this is just it, his father was not on the birth certificate, he was an illigitimate child, he did have a brother named tom Corbett though, i dont have details as of yet but will try my hardest.
Two surnames? yeah that is odd (his mothers name was Agnes Stephens) its hard to find out info as my nan was young when her mother (agnes) died
Thanks for replying though, can be really difficult finding help
