This is a response I received from the Detroit Society for Genealogical Research:
Your letter came at an interesting time! Some years ago we printed a
two volume set of Catholic records from the Detroit area. This year we are
planning on printing the marriages of Ste Anne 1701-1851 (Ste. Anne was the
only Catholic church in Detroit until 1840). I checked the two volume set and
the original records of Ste Anne. There is NO record of a marriage of a
Stephen Dupray marrying a Mary Moisan 29 April 1825! However, there is a
recording of a Stephen Dupray born LaPrairie de la Magdelaine marrying a Mary
Moisan on 29 April 1805!! This is his second marriage.
If you'd like to order the two volume set go to our website at www.dsgr.org
