Bouvier's Law Dictionary, Revised 6th Ed (1856):

FILIATION, civil law. The descent of son or daughter, with regard to his or her father, mother, and their ancestors. 2. Nature always points out the mother by evident signs, and whether married or not, she is always certain: mater semper certa est, etiamsi vulgo conceperit. There is not the same certainty with regard to the father, and the relation may not know or feign ignorance as to the paternity the law has therefore established a legal presumption to serve as a foundation for paternity and filiation. 3. When the mother is or has been married, her husband is presumed to be the father of the children born during the coverture, or within a competent time afterwards; whether they were conceived during the coverture or not: pater is est quem nuptice demonstrant. 4. This rule is founded on two presumptions; one on the cohabitation before the birth of the child; and the other that the mother has faithfully observed the vow she made to her husband. 5. This presumption may, however, be rebutted by showing either that there has been no cohabitation, or some physical or other impossibility that the husband could be the father. See Access; Bastard; Gestation; Natural children; Paternity; Putative father. 1 Bouv. Inst. n. 302, et seq.
