The lots were also realigned to conform to the City survey. As well, the street numbers assigned to the Insurance Maps prior to 1936 were added after the street numbers had been standardized adding to more confusion. In addition there were "fuzzy" memories which added to the mix. The initial Heritage Register researched the property, I researched the property three times, and then I researched two more times with Shawn Lamb, Archivist, to ensure accuracy.

This structure was not in the 1899 Assessment Rolls for the City of Nelson (03 May 1899), but appears as of July 1899 on the Fire Insurance Map. The structure was erected between the 04 May 1899 and 31 July 1899.
By 1901 the structure has disappeared. It likely burned down or was just removed. As Dr. Arthur was involved with the local fire company I would not be a bit surprized if it was used in a fire drill.
In 1913 the property was purchased from Dr. Arthur by William J. Murphy. There was no house on the property. A house was built on Lot 14 between the end of May 1914 and the date of the new assessment in 1915. The 1915 Directory for the City of Nelson shows the Murphy family at 723 Latimer Street.
In 1915 the assessed value of the house was $2500.00, while lot 13 was $330.00 and lot 14 $245.00. The house was built on lot 14. Please note that the lots on Silica Street and above are approximately one and one half lots in size. When the city was first surveyed the lots below Silica were more standardized, thus smaller. It does not appear that the Insurance Maps took this into consideration or perhaps, they too had the numbers added at a later date.
To add further confusion Nelson often changed the physical addresses of the houses on the corners of cross streets. One year they would be located on, for example, Latimer and the next year on Hendryx. This was common practice until the city formalized the city survey.
By 1919 the house and property are in the name of Lydia A. Murphy", wife of William J. Murphy.
William James Murphy died on September 17, 1919 at the age of 63 years. As Mr. Murphy died after a lengthy illness it is likely he died at the home.
Mrs. Murphy purchased Lot 15 in the interval between the 1924 and 1925 Assessments. The lot was owned by A. L. McCulloch, the City Engineer.
*In 1873 women who owned property in British Columbia became the first in Canada to secure the right to vote in Municipal Elections.
