The entry is for Edward Branwell, aged 8, in Tipton, Staffs. (RG9/2041 ED2 FOL34 PAG16), so he won't be on th 1851.
Father George is a railway labourer, and obviously moved around.
I've had a look for others with Boscot as their birthplace. Only a few in 1861, and virtually all in Liverpool.
One of them appears in 1871, when his birthplace becomes "Burscough".
The local pronunciation matches well, and you wouldn't expect anyone in Tipton to have heard of the place.
It has two railway lines too.
