No, whilst Yorkshireman Wilfred Batty (born in Bradford) shot the last individual known to have been killed in the wild it was not the last Thylacine known in the wild. The Batty shooting occurred on the 13th May 1930 but two juveniles, a male (7th July 1930) and a female (3-9th August 1930), were captured later by the Delphin family of Waratah, who were of French-Mauritian extraction. Whilst those captures were publicly reported, put on public display, and in the case of the male, displayed at a public zoo between October 1930 and September 1936, there's strong evidence that a further individual was later captured in a rabbit trap at Preolenna in early 1931. Incidentally, full legal protection in 1936 was also instigated by a Yorkshireman.
