I've seen the scans and they are very clear but confusing.
The author may not have made a mistake but the printer could have.
There are two George Barnsley born around the same time, one married to Elizabeth and the other to Asenath.
The one married to Asenath is not the George who died in 1895, his occupation is a Table Knife Hafter, and George Barnsley 1837-1895 was indeed married to Elizabeth and was made a partner in his father's company in 1858.
George Barnsley married Elizabeth Miller August 20 1856 in the parish of St Bride London. His father is listed as George Barnsley. Manufacturer
Elizabeth's father is listed as Gentleman.
