Washington, U.S., Death Records, 1907-2017

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 2/4, tier record.
The 1948 Washington death certificate for Arthur A. Wood (born 24 Mar 1870, Grand Beach, Quebec) lists his mother's maiden name as "Marie Ann Spackman," born in England, and his father as Franklin Wood. This supports the name form for the mother, though the spelling varies slightly. It does not give her dates, and the informant was only coroner's records, so it is thin for the full claim.
Matches: Mother's maiden name on the certificate reads "Marie Ann Spackman" (handwriting appears to read Marie/Maria Ann Spackman), a variant of Maria Anne Spackman; Mother's birthplace is given as England, which is plausible for a Spackman; Informant/mother entry is on the death certificate of Arthur A. Wood, born 1870, which fits a mother born 1824 (age 46 at his birth)
Limits: The certificate names her only as the mother's maiden name; it gives no dates for her, so the 1824–1907 life span is not confirmed; Spelling is Marie Ann rather than Maria Anne; the handwriting is somewhat unclear; Informant was coroner's records, so the information is secondhand and may be unreliable; The certificate does not identify her as a specific person beyond being the mother of Arthur A. Wood, so her identity depends on other evidence; Her birth place is given only as England, with no town or county
