 Stourbridge
 ROBBERY BY RAILWAY SERVANTS - At the Police Court, on Thursday afternoon, William York, railway watchman, James Harris, engine drivere, and Daniel Boucher, stoker, were charged with stealing 2½ gallons of whisky, the property of the Great Western Railway Company, on the 20th March. A boy named James Brown, also a servant of the Great Western Railway Company, was placed in the dock with the prisoners, but as there was no evidence against him he was at once discharged. Mr Bentley (or Worcester) appeared to prosecute, and Mr Burbury for the prisoners. Mr Bentley stated that on Saturday night last York was a night watchman at the Stourbridge Railway Staion, and his duty was to be there from seven o'clock at night till seven on Sunday morning. Harris on Saturday night drove a goods train from Bushbury Junction to Worcester, and in one of the trucks of the train was a case of whisky. Boucher was the fireman of the train, and a man named Shewards, who has since absconded, was the guard. The cask in question was for Mr Malpa, wine and spirit merchant, of Worcester. The train arrived at Stourbridge Station somewhere about ten or eleven on Saturday night, and remained there about an hour.  During that time the cask of whisky was tapped, and two gallons were taken out. Having stated further particulars with regard to the caes, Mr Bentley called his witnesses. ON of them (Sergeant Booth) said he met York near the Stourbridge Railway Statio on Sunday morning. He was carrying a can, which he said contained coffee, but which the witness found to be whisky. He took him into custody on the charge of stealing it. He went to Worcester on Monday morning, and apprehended Harris. Afterwards he searched Boucher's house and found two bottles, each containing a pint and a half of whisky. After his apprehension York told him that he guard of the trains, Sheward, had instigated him to commit the robbery. Mr Bentley then asked for a remand till Tuesday, which was granted.

Daniel is known from family sources.
He and Sarah are with their daughter Elizabeth Mary in 1871 and her baptism also gives their names.
His place of birth is consistently given as Elmley Lovett and there is one baptism at this time.
Daniel is a relatively unusual name and his marriage to Sarah is the only likely one which also gives the names of both their fathers.
Thus the identity of Daniel is certain.
