These are two different Puddlers Row. The 'old' Puddlers Row is also shown on the 1859 map but unlike the 'new' Puddlers it is on the east side of the main road. The old Puddlers Row belonged not to Bedlington Station/Sleekburn, but to 'Village of Bank Top', according to census information, and was there before Glassey's arrival in 1867. It appears in the 1871 census as a row of 22 dwellings.
Glassey left Bedlington in 1884 and the old Puddlers Row still appears on OS maps in 1898 but without a name. On the same map the new Puddlers Row appears running east-west along what later became Stead Lane. We can also see here that the west side of the road, north of the Bank Top Hotel, is still not developed.
At some point between 1897 and 1922 we can see a devlopment on the west side of the road - the area now occupied by Glassey Terrace. This is called Front Row. New development on the east side of the road in the area of the old Puddlers Row, includes a 'Back Row' and what could be old Puddlers Row but with an extension. By 1947 Puddlers Row is no longer shown on the OS maps and Front Row is still called Front Row - not Glassey Terrace.
