This is deffinetly not 'my' William Clark. The Clarks are such a huge family from the loyalist immigration and many of the Clarks had large families of 10-13, mostly male. There are a number of William Henry Clarks as well. I do know for sure my William married Mary Elizabeth McConnell. His parents were Lewis Clark and Hester Jane Montgomery of Portland Township, Frontenac County, Ontario, Canada. Her parents were Joseph George McConnell and Amanda Elizabeth 'Mandy' Boice or Boyce. Many of the family can also be found in Ernestown, Lennox and Addington County, Ontario, Canada.
