It all adds to the big picture and the use of matrimonial agencies more widespread than I would have imagined. So, there were "normal" procedure using churches, then the matrimonial agencies and registry offices. Have to look at the relative costs of each option and consider what the reasons were for couples making particular choices.
It also occurs to me that it was a good option for ministers of religion to receive payment from the matrimonial agencies, rather than get nothing at all. I wonder how it was entered in the bookkeeping of the respective churches?
By the way, have located a 15 page brochure or booklet at the State Library NSW issued by World's Matrimonial Institute - have to find a day when I can get in there to have a look. J
