I too have a copy of these records. at the time of this entry the records are very erratic. the previous year Daventry had no boat inspector. The entries for 1904 are very different in nature, so much so that I suspect that some, if not all, of the entries have been made up. The entry in the register on 31 Oct 1904 says " Hope to see more work done when a proper inspector comes". I was surprised to find so much information on the Linslade.
Also, Sophia Brace is recorded on a narrowboat in the 1901 census at Simpson, nr Fenny Stratford (about 1 mile from where I am writing this!) with her husband John (44) son John (19) daughter Ada (16) and son Albert (10), son Horace (or daughter Florence) aged 8. All listed as born Worcester, Son Benjamin (6), daughter Beatrice (4), daughter Olive (6months)
