Here is a bit of twist! Is this Annie Cobb? On the site it says last name is Bartlett but I cannot see it on the headstone. See what you think. On 1901 census Annie's birth date is given as 8 Dec 1868.
On the below site, you can view the headstones of James and William Bartlett [d 1941]. Also there is a headstone for a Louisa , sister of Jim and Will, b 3 Dec 1865, died July 18, 1962.[or maybe it says 1952]
