Hello Bruce! I have information as well on John Sunderland. It is all on computer. However, I can always copy and paste it here as well for his Military career.
We follow the same line but it must split somewhere for certain. However your last name is Mitchell. And my Great-Grandfather's Surname was Mitchell as well. Hence how I am related to the Sunderlands/Sunderlinds.
I'm looking for the parents of Daniel Sunderland b. 1680 in Yorkshire, England. Have you perchance got this information?
Please feel free to e-mail me at firstname.lastname@example.org if you wish to discuss further or leave a message here. thanks! Amanda
