There is a Roderick McDonell listed on the reconstructed list of the Pearl voyage of 1773 that I have from the Chisholm Clan webiste; however, it states that he was a UEL and emigrated in 1774. But, send me a message to: firstname.lastname@example.org
with your e-mail address and I will send you the list as it is a Word file and this system will not accept sending it as an attachment. I have heard of Roderick "Rory" MacDonell / McDonell who married a Mary Chisholm and was granted crown land. What documentation do you have on Rory?
