Hi Brendon. Deslauriers may be translated literally by "of the laurels". Laurels are the symbol of victory and may have been used by soldiers such as your ancestor Noël Legault dit Deslauriers. There is hardly any documentation about aliases and it is impossible in most cases to determine the background of each individual name. Only in limited instances can one pinpoint the origin let alone the meaning. I have seen several persons on the net and elsewhere try to explain or attribute a meaning to those names, without any proof of what they are stating. Also don't forget that signification of words has evolved over time and that names and expressions used 300 plus years ago may have a different flavor today. Interpretation of surnames is a very slippery road. I have seen Legault spelled "Le Goth", evocating the old Goth barbarian tribes that invaded Europe at the beginning of the christian era and were among the factors that caused the decline of the Roman empire. I doubt that this points to the origins of your family though. This may be a local joke at the time and may have a relation to physical appearance or character of an individual in that family. Anyway, in most cases it is gesswork and supposition and not based on solid ground. Beware. I am not an expert in this matter but in most of the cases I have seen the name usage evades any explantion other than what I have said here and elsewhere.
