MULIER. A woman, a wife; sometimes it is used to designate a marriageable 
virgin, and in other cases the word mulier is employed in opposition to 
virgo. Poth. Pand. tom. 22, h.t. In its most proper signification, it means 
a wife.  
     2. A son or a daughter, born of a lawful wife, is called filius 
mulieratus or filia mulierata, a son mulier, or a daughter mulier. The term 
is used always in contradistinction to a bastard; mulier being always 
legitimate. Co. Litt. 243. 
     3. When a man has a bastard son, and afterwards marries the mother, and 
has by her another son, the latter is called the mulier puisne. 2 Bl. Com.
