Samuel was born in Wigton in Cumberland in 1889, the son of Obadiah and Ruth Bird Teasdale. They were living at Newlands, in Bolton, Cumberland, in 1891, together with three servants – John Coulthard, James Turnbull and Jane A. Scott. They had moved to Brafferton in Yorkshire by 1901, and Samuel had gained two brothers – George and Wilkinson – and a sister, Constance.
At some point, Samuel moved to Wolverhampton and became a police officer. An entry in the Chief Constable’s Report Book on 3 May 1915 states that 1 Superintendent and five constables “Have rejoined the Army since our last meeting”, and Teasdale is one of the names that is listed. Samuel’s marriage to an Annie Baker is registered in Wolverhampton in June 1915, so presumably he married her before he left for the Front.
Samuel was a 2nd Lieutanent in the 10th Battalion of the York and Lancaster Regiment. Unfortunately, on 3 September 1917, the following entry appears in the Report Book:
The C. C. [Chief Constable] regrets to report that official notification has been received respecting 2nd Lt. Teasdale who was killed in action.
He was killed in action on 31 July 1917. He is commemorated on the Ypres (Menin Gate) Memorial.
