Alex and Annie
I like the ring of those names together, and I guess they did too.
Alexander Roberts and Anne E. Slingerland were married on 17 March 1852 in West Oxford, Brock District, Ontario, Canada. Theirs are the last names on this list of marriages performed by Isaac Elliot, Pastor of the 2nd Regular Baptist Church.
Alexander Roberts and Anne E. Slingerland Marriage Record
You can see in the 4th column that this couple was married by the authority of “Banns,” instead of a license. The banns of marriage, are the public announcement in a Christian parish church or in the town council of an impending marriage between the two persons indicated. Traditionally banns were read from the pulpit on the three Sundays prior to the wedding.
The purpose of banns was to enable anyone to raise any religious or civil objection to the marriage, so as to prevent marriages that are invalid. Objections vary between legal jurisdictions, but could include a pre-existing marriage that has been neither dissolved nor annulled, a vow of celibacy, lack of consent, or the couple’s being related within the prohibited degrees of kinship.
