Isabella Maclean (born 1797) lived in Gress Tack, but it is not certain she was born there.

Isabella married Donald Murray and the couple had two children at an unknown location.

In 1830 the family obtained 15 Old North Tolsta as a newly lotted croft. The couple had a further three children there. In total they had five children: three boys and two girls.

In 1853 the family emigrated to the Eastern Townships of Quebec.
