52.—In French names the entry should not be made under the prefix “de,” but under the name next following it, unless the “de” has become so much embodied in the surname as to be an integral part of it rather than a prefix. If the prefix happens to be the definite article “le” or “la,” or the article is comprised in it, as “du,” then the entry is to be given under the prefix. The following names show the part of the name which leads off:
Maupas, C. E. de.
Decourcelle, A.
Delaroche, Paul.
La Bruyère, Jean de.
