Barker, the son of Clarentine and Magnus Flett, is a botanist who becomes an important figure in Daisy's life. His journey from bachelorhood to family man is marked by his passion for botany and his complex personal relationships.

Cuyler is Daisy’s father, a stonecutter in Manitoba who becomes known for building a stone tower in memory of his wife, Mercy. His life reflects themes of grief, love, and self-expression through his work with stone.

Magnus, Barker's father and a Scottish immigrant, is a stonecutter whose life takes him from Canada back to the Orkney Islands. His character is defined by his introspective nature and his later life in Scotland.

Clarentine is Barker's mother and a close friend of Daisy's mother, Mercy, taking on the role of Daisy’s caregiver after Mercy's death. She is an independent woman with a successful florist business in Winnipeg.
