I have an earlier Wilkenson in my tree, if you find she is in your tree I have some descendancy and a lot of collateral relations of hers-though not Wilkensons, I relate to her husband's family.

Mary Wilkenson
b. unknown
d. 21 Mar 1745 Woodbridge, St. Mary's, Suffolk
m. 11 Feb 1738 in Suffolk
Peter Cross
she and Peter slipped in and out of the Quaker faith so information on them is spotty.

there is a Robert and Judith Wilkenson in Kelsale in the right time frame to be her parents. they lost a baby named Mary, I don't know if they had another child.
