Home District Marriage Register (1831-1857) has John Tomlinson marrying Sophia Thomson both of Markham 11 April 1839 by liscense by Rev David Youmans Wesleyan Methodist; witnesses Alfred Tomlinson & Mary Yeomans. HDMR Vol 1 p 383.
The above and family lore had Sophia's name as Thompson.
James Tomlinson had children with Sophia and Wheelock as middle names.
Sophia's husband John was thought to have a middle name of William - in one instance a record shows Wheelock.
Several family trees on ancestry have Sophia's middle name as Wheelock.
Obviously there is a Wheelock somewhere in this family. But where?
