Early life and career

Marit Stiles was born on September 20, 1969, in St. John's, Newfoundland, growing up in the communities of Long Pond and Logy Bay. The name Marit is of Norwegian origin, although Stiles does not have Norwegian ancestry, and the name was suggested by Norwegian family friends. Her parents were Americans who had moved from Pennsylvania to Newfoundland in 1967 and settled on a small organic farm outside St. John's, growing vegetables and raising goats, chickens, geese, rabbits and pigs. Her father was an anthropology professor at Memorial University, who later became an energy conservation consultant in Canada and Africa.

Editorial analysis

Why this record matters

“Marit Stiles” is worth following because a concise public description often conceals a longer documentary argument. Here, Marit, Stiles and Leader provides the most credible route into that argument.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 4, 2026. The linked authority identifier is Q54862567. 1 of 5 selected statements include explicit references; 4 carry qualifiers and 2 use preferred rank. The first chronological checks are 1969, 2023, 2018 and 2014.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
