That depends on whether the marriage record is from the one recorded in the City of St. Louis Marriage Records or the one in the St Boniface Marriage Register. The St Boniface record would show names of parents of both husband and wife and other details such as witnesses, etc. The city record may or may not be done by the same priest that married them and the church records usually have much better handwriting. The priests only recorded marriages at city hall when they felt they had enough marriages to record that warranted a trip down to city hall and they were quick about these entries with sloppy handwriting so they could get back to more important parish work. Also, since she married at St Boniface, it is very likely that she was baptized there, so it would be more likely a full name would be on her baptism record at St. Boniface. Since St Boniface closed, all of their records were transferred to the Archives at Kenrick, but films of some registers are at the St Louis Lindbergh County Library.
