I may be on the wrong track

Now I have figured out who owned/started the Stonemasons Business;
"Established in 1899 by William Lambert Cookson, the firm of WL COOKSON Ltd is a family business, renowned for personal and first-class service throughout the Blackpool, Fylde and Preston areas and beyond."
1901 Census
6 Jackson St,
Blackpool, Lancashire
RG13/3972/68/19
William L COOKSON, 25, Head, Mar, Monumental Sculptor, Own Account, born Blackpool
Jane Cookson, 25, Wife, Mar, born Preston
This William does have a Brother THOMAS born c 1887, Blackpool.
1891 he is a Scholar and 1901 a Bricklayers Apprentice
Parents JAMES Cookson and Mary Ellen CHARNOCK who Married June 1874, Lancaster, 8e 1050.
As I said earlier the Marriage Cert of Thomas/Maud is a must buy!
