JACKSON families of Ontario

Hi, Is anyone related to or have info about these Jackson families?

http://www.jacksonpublications.com/jacksongenealogy.htm

I am interested in the third Jackson family listed DESCENDANTS OF HENRY JACKSON
(1606 - 1686) aka the Jethro Jackson family of Richmond, Ontario. Jethro's daughter Fanny
listed here was the wife of my John Pencil, Jr. I have tried all three e-mails
on this website but have never received a response.

Does anyone one know if these researchers are still active in genealogy? I would
like to contact them. Are they on Ancestry.ca? I don't have either Ancestry.ca
or Ancestry.com.

Thanks,

Loretta Pensyl Lisowski
