He appears a lot on Ancestry - marrying Eleanor Dodds in 1899. A birth of Charles Frederick Nutman, presumably a son, in 1901. In the 1911 census his wife entered him on line 1 but crossed it out - he was not in residence that night. He is a seagoing fireman. By then 2 daughters, 4 children born of the marriage, one has died presumably the son as another Charles Frederick is born in 1912 but dies immediately.
In 1929 he is seaman arriving from Bombay on the Macedonia age 51, residence Cardiff. So we might assume that he had a second marriage to Maud Hyett in 1917 in Cardiff. However I can't find a death of Eleanor Nutman before 1920. So lots of information around 0- there is more - but lots of research needed.
