if you check the free search on the 1921 census, the family is in Redruth.
Joseph is born 1876 in Taunton & Jane 1882 in Dorchester Dorset. Children Alice b. Bristol 1905, Tom b. Redruth 1909, Louie b. Dorset 1911, Mathew b. Redruth 1913, Joseph b. Par 1915, Elizabeth b. Redruth 1916, Sam b. Redruth 1918, Polly b. Redruth 1921.
When did they marry? You have a date on the tree for the marriage that is after the death of Joseph.
Do you have a copy of the marriage certificate to confirm names of their fathers & their occupations?
The 1939 register gives a date of birth for Janette of 19 Aug 1880 which is more likely than 1870 given that there was a daughter born in 1925.
