To Know if a Woman with Child will Have a Girl or Boy (Spell)

From Madam Le Marchand's Fortune Teller and Dreamers' Dictionary:

To Know if a Woman with Child will Have a Girl or Boy

Write the proper names of the father and the mother and of the month she conceived with child, and likewise adding all the numbers of those letters together, divide them by seven; and then if the remainder be even, it will be a girl; if uneven, it will be a boy.
