Many thanks go out to Suzanne Sommerville for this contribution regarding the French pronunciation of native names.
Note: wherever you see an *, this symbol should replace it: 
The record of marriage of Pierre Couc dit Lafleur de Cognac and Marie Mitè8amèg8K8è, an Algonquin Indian, exists in two forms, one a beautifully handwritten transcription (copy)[1] of the original record, and the other the original register itself in Latin.[2]
16 April 1657 Marriage Record at Trois Rivières, Drouin Collection on Ancestry.com
Translation into English:
In the year of our Lord 1657 on April 16, I Paul Ragueneau, priest of the Society of Jesus, after having announced the three bans of marriage according to custom during the celebration of masses in the Blessed Virgin Chapel in Trois-Rivières, having questioned them and received their mutual consent by word and by their presence, I united in marriage Pierre Couc dit [usually also known as] Lafleur, son of Nicolas Couc and Élizabeth Templair of the parish of Cognac; and Marie Mitè8amèg8k8è, Algonquin by nation; Algonquin witnesses were Charles Pachirini and Barthélemy Anara8i; French witnesses were Mr. Péré, merchant, and Mr. Ameau dit St. Séverin.
On this record, what looks like an /8/ is actually a Greek upsilon [υ] on top of a Greek omicron [ο], producing a symbol which the Jesuits and other officials used to represent a sound not found in French, close to French /OU/ or English /W/ before a vowel.[3] When this symbol was transcribed and printed for publication, no appropriate equivalent was available to the typesetters, so the numeral /8/ was chosen to take its place. PRDH always transcribes the /8/ as /OU/. On the original handwritten documents the symbol looks somewhat like this Microsoft Word© Wingding 61535, [*] See the record above and below for its actual form.

[3] The “u” above an “o” is a Greek upsilon [υ] combined with an omikron [ο] to represent the sound. Only by using the international phonetic alphabet would we come close to reproducing what the Jesuits heard. E-mail from Fr Owen Taggart, pen-name of Father John Sullivan, 8 July 2002: “The pronunciation of /8/ . . . sometimes represents the vowel-sound [ou] of the French language, and sometimes the consonantal [w] of English (which does not exist, and is “unimaginable” for French speakers to distinguish from the [ou] sound). It is incorrect to merely substitute the /8/ by a [ou] for a very simple reason: The /8/ represents two distinct phonemes. Sometimes, the transcription [ou] is correct, but sometimes, it is correct to transcribe with [w]. It is really unfortunate that the written transcription /8/ has disappeared, since it reminds us quite pointedly that the precise phonemic pronunciation of /8/ is distinction both from the usual pronunciation of both native French and native English speakers.”
