I am trying to find the meaning of the initials A.M. after the name of Benjamin Blackford of New Jersey in 1808. He is the person who performed the marriages of a number of couples around this time period, and all his signatures include the AM after his name. I was thinking that the initials might help me to identify the location of the marriage ceremony he performed on a couple I am researching. Does it indicate a church affiliation, or is it another professional designation, like a Justice of the Peace?
Thanks very much for any help you can offer.
