Hi Menwuk,
I've been unable to locate a Charles Willcox b.1887 with brothers Thomas and Job. On FreeBMD there is no birth record of Charles Willcox c.1887 in the county of Somerset.
There is however a Charles Willcox b.1881 with brothers Charles and Thomas (it looks as if he was actually born Jasper Thomas) living (1891 and 1901 census) and born in Peasedown St John.
1891 census - RG12/1928/24/41 Living in Camerton/Peasedown St John,
Job Willcox head, age 31, coal miner, b. Camerton
Sarah, wife age 33, b. Radstock
Charles, son age 10, b. Camerton
Jasper T, son age 8, b. Camerton
Job, son age 6, b. Camerton
Elizabeth, dau, age 4, b. Camerton,
Rosa, dau, age 2, b. Camerton
Ann, dau, age 1, b. Camerton
1901 census for the same family but Charles is missing - RG13/2335/132/33 Living at 9 Fairfield Cotts, Camerton and Peasedown St John
Job Willcox head, age 42, coal miner hewer, b. Peasedown
Sarah, wife, age 45, b. Radstock
Thomas, son, age 18, coal miner below b. Peasedown (Jasper T from the 1891 census)
Job, son, age 16, coal minert below, b. Peasedown
Lizzie, dau, age 14, b. Peasedown
Annie, dau, age 11 b. Peasedown
Frances, dau age 9, b. Peasedown
Kate, dau, age 7, b. Peasedown
Ada dau, age 4, b. Peasedown
Do you think that this is the family you are looking for? If so we can then build a picture from there.
