For those who aren't canadian history buffs, here is what a Fille du roi is:
Fille du Roi (King's Daughter), a program sponsored by Louis XIV to encourage young single women or widows without children to emigrate to New France. The expression Filles du Roi was coined by Marguerite Bourgeoys to designate Louis XIV's sponsorship progam for populating New France, including in terms of a dowry for each Fille du Roi. Between 1663 and 1674, close to 800 Filles du Roi were recruited to go to New France.
Under the program, the Louis XIV sponsored paying the transportation of, along with a dowry for, the daughters. As a rule, the dowry was equivalent to 50 livres for marrying a commoner and as much as 100 livres for a girl marrying an officer, the total being roughly equivalent to $1,425 in 2000 currency. In addition to having the costs of her passage paid by the state, each daughter received an assortment of practical items in a case: a coiffe, bonnet, taffeta handkerchief, pair of stockings, pair of gloves, ribbon, four shoelaces, white thread, 100 needles, 1,000 pins, a comb, pair of scissors, two knives and two livres in cash.
Almost two-thirds of the daughters had lost one or both parents with many coming from convents or hospitals where they'd been placed as orphans and other poor commoners.
In France, fathers found husbands for their daughters, who married who they were told to marry. Things were different in New France, since there was a lopsided large number of single men compared to the number of marriageable females. The New France administration had penalties for single men, but provided more attractive benefits to married couples, including financial rewards to families with many children. Single men would sometimes spend a year or more getting their house ready for their new bride to be.
