Hector Morrison of Morvern, married Marion McLean of Ardnacross, both of the Isle of Mull, Scotland. They had eleven children, ten of whom were born in Scotland. In 1806, Hector and Marion emigrated to PEI and settled in Flat River. Neil Morrison from the Isle of Mull, whose Morrison family members on PEI corresponded with, was probably Hector's brother who remained on Mull and never married. This Morrison family was related to the Rankin family through the marriage of Coun Douly Rankin to Flora Morrison.

He and Catherine had six children, including Coundulli (later spelt Coun Douly). Born ca. 1774 at Breachacha Castle, Isle of Coll, C. D. Rankin, as he was often known, married twice, first to Flora Morrison (d. 1814) in 1804 in Coll (the couple had five children) and later to Margaret McLaine in 1818 in the Isle of Mull, Scotland (the couple had seven children). C. D. Rankin first came to Prince Edward Island in 1806, and over the course of his life lived in Charlottetown, Belfast, and Point Prim. C. D. was a member of the Legislative Council from 1806 to 1810, as well as a sheriff and militia commander. C. D. Rankin died on the 4 February 1852, in Charlottetown. C. D.
