Joseph Bennison and Hannah Scarrow are my GGGGrandparents.
Frank Scarrow Bennison was baptised August 23rd 1826. His parents Joseph and Emily Ann Bennison nee Lee. They had 6 children : Hannah Eliza (Lillie)1869 Ceylon, Alice Maud 1872 Ceylon, Joseph James lee (Lee) 1875 Ceylon, Frank Scarrow 1876 Chester, Percy John 1878 Chester, Helen Muriel 1886 Frankby, Chester.
I believe Emily Ann Lee met Joseph Bennison at her brothers marriage Thomas Lee to Ann Elizabeth Bennison in 1863.
I haven't found any William in this family.
If there is anything else I can help you with please let me know.
