Hogg was born in Ballymena, Northern Ireland and is best known as the lead singer and songwriter with the christian progressive (or cprog) celtic/pop/rock band Iona (named after the island Iona). Her father is a Presbyterian minister, her mother a nurse; her family also includes three sisters and two brothers. With medicine strong in the family, it was natural for Hogg to become a doctor. Thus, she studied medicine at Queens University in Belfast.
