Marriage at St. William We welcome couples to schedule a wedding at St. William Parish. At least one of the engaged couple must be a baptized Catholic. Couples are asked to contact the church at least six months in advance of the desired date of the wedding. This is so that you have the necessary amount of time to prepare for this most important sacramental event, in which you lay down your lives for one another. Please call the Parish Office and ask for Fr. Jim at 608-755-5180.
