Corroboration only, nothing changed. The tree's 8 APR 1879 - 30 AUG 1952 and the parents John Douglas / Sarah Hickey match this article exactly. A death year of 1917 was flagged for this person; no such year appears in the article, whose infobox reads death_date 1952-8-30 and which is categorised under 1952 deaths. The tree value stands.
