I'm wondering why the name of William John Sparrow Simpson is given as Sparrow-Simpson (SparrowSimpsonWJ). The only source cited is Julian, who calls him "Mr. Simpson" and doesn't hyphenate the header. Wikipedia agrees and uses "Sparrow" as if it were his forename. It was apparently his father's middle name.
Now on the other hand, Julian supports hyphenation of "Elizabeth Rundle-Charles", where our database treats calls her Charles_ElizabethRundle, and beginning in his Appendix (but not in the original dictionary) Julian calls her "Mrs. Rundle-Charles" and indicates that she preferred that form.
