Looking at James' siblings from the above 1901 census this may be James on the 1891 with the name Dukson

However the name Dukson sounds similar to Dixon-
John F Dukson head 35 b. Scotland. Rolleyman
Phillis Dukson wife 33 b. Berwick upon Tweed
James Dukson son 10 b. Berwick upon Tweed
John Dukson son 8 b. Berwick upon Tweed
Margaret Dukson dau 6 b. Berwick upon Tweed
Samuel Dukson son 4 b. Berwick upon Tweed

Phillis Forrest wife 26 b. Berwick Upon Tweed
Barbara Forrest dau 6 b. Berwick Upon Tweed

Therefore i suggest that James was originally born Forrest/Forest but his parents decided to 'adopt' the name Dixon.
All of this gives 'food for thought' I do appreciate you have yet to establish the correct James, however all the above information may be of help to you in the future
