Alex mclennan married Ann mackenzie 1805

Hello,
I am trying to find out if I am related to the Alexander Mclennan who married Ann MacKenzie in applecross on 27 nov.
1805.
My great grandfather Neil mclennan came to Ontario canada
along with his brother Alexander in the late 1840s.

I know there Parents name is Alexander mclennan and Ann Mackenzie but that is about all.My great grandfather was born in Rosshire.My grandfather neil was born in 1813 and his brother alexander around 1819.

Thanks
