I looked at the ScotlandsPeople site. I can only look up records, I don't have enough credits to view each one.https://www.scotlandspeople.gov.uk/
I found a Hector McDougall born 18 January 1801 in the parish of Tyree and Coll, Mull. Parents were Angus McDougall and Flory McKinnon.
I looked up Ann/Annie MacLean but there were five on the list born in 1808 and many more in the years just before and after 1808.
Hope that's of some help.
