Hi
I am not a member of the Shambrook family, BUT, I have been checking out the headstones in Fremington churchyard.... eventually to send to the gravestone project.

It is still a work in progress, having photographed approx 1/2 the churchyard.
Anyway back to the plot, if it is any use to anyone I have found a headstone for the following branch of the Shambrook family.
Mary Shambrook died Nov 1st 1903 age 69
husband William Shambrook d. Aug 12th 1913 age 81
son Thomas Thorne Shambrook d. Jan 13 1939 age 76.
