Thank you Pam and very grateful Ian, you have correct Alexander 1901 census am lookin for.
I found most of those children, apart from last 2 born. Now I have an address. I am fairly sure Abel was Alexander, he 20 stated coal miner born Sunderand on 1881 census as boarder at Railway Inn, Castle Eden - he cannot be the other Alexander's born at Sunderland,I have data those there, however Castle Eden was link with "Abel's" parents living there in 1864 when the father William Snowball died. Maybe was a transcription 1871 census mistake, Alex named as Abel, not found anything later for Abel.
The Snowballs had earlier connections with Witton Gilbert and Sunderland.
Mother Margaret H Corner had remarried 1866 & by 1871 census was a Widow using 2nd husband's surname Stephenson and with her were William Snowball's children including "Abel".
Many thanks everyone for help.
