The common spelling for the surname in Quebec is Lecuyer or
L'Ecuyer. The pronunciation sounds like Le-qwe-yay.
My brother-in-law's nickname is Lec like in Lech Valensa.
If you are searching the Drouin Quebec Vital Record data on
Ancestry.com or Ancestry.ca their indexing of the data is terrible. Various surnames that proved to be Lecuyer are:
Delphi L Ranger; Marie St Anger; Samuel Eanque; David Leciner;
Jenne David Levine for Jena David L'Ecuier; Samuel David Limoges.

I start by searching for the marriage document using Given name of husband and surname of wife. If the hit list is too large I add year and range + place of worship. Of course this means that I start with some data that I've gleaned from genealogy repertoires or internet searches. I've found that if somebody has a date and/or place that they got it from some record that originally started with the document.

For baptism or burial I start with Surname+place+year+year range.

Good luck
Tom
