Hi Mandy
It is a good book. My G Grandfather Samuel Evans and his father Evan are both in the book. I have a Griffiths family in my tree don't know if it ties in with yours.
William T Griffiths born abt 1851 married Mary Ann Bowcott & they had 7 children - Mary Jane, William T, Eleanor A M, Clara E, David John, Laura Ann M & Edgar B.
best wishes
