Re: LESASSIER SURNAME MEANING
The surname is from French le sassier. Sassier is an Old French word derived from sasse 'sieve, strainer' so this was a nickname for someone who made these items. In short, le sassier means 'the sieve maker'. You'll find information on Jean-Charles Lesassier at tinyurl.com/hlw8n5r and tinyurl.com/pnldstq, inter alia.
