I have found a Charles Wells in the Utah Cemetery Inventory on A... Born 7 Jun 1853 in England, died 28 Jan 1933, buried in Provo City Cemetery, Block 8 lot 105,wife Jane. In the 1910 census, he and Jane have a slew of children:
Thomas, 23
Lucilla 20
Walter 17
Helena M 16
Edith E 14
Ethel M 13
Ellen L 10
They were all born in England. This Jane died in Feb 1919, so this next Charles could be the same one, remarried.
There's also another one in Provo in the 1930 census, wife Frances M., age at first marriage 25 for Charles, 20 for Frances, although he is 76 and she 65, so this would be their second marriage.
In 1920, there is a widowed Charles living with his kids Maud, 26, and Mary, 23. They came over about 1908.
Let me know which one you think is the correct one and I will look a bit more.
