In 1936, female lawyers were rare enough that the September 18 edition of the Toronto Daily Star saw fit to include a picture of one:
The problem with tracing women in the Toronto city directories is that the directories do not list married women. So it is with Ms. Haughland: she was listed in the 1935 directory as a student at law (as “Edith”). The 1936 directory omits the Haughland family entirely, but the 1937 and 1938 directories list Edythe Haughland as a lawyer. After that, she presumably appears under her married name, if at all.
(For those of us, like me, who aren’t all that literary: Portia is a character in Shakespeare’s The Merchant of Venice.)
