I would not put down a full date unless I obtained it from a written record. The Belleville Public Library has computer print outs of all the recorded marriages in Hastings and Prince Edward Counties. My notes are packed away and it may be a couple of months before I can get to them. If you can't find it by then, let me know. Good luck, and rest assured that the date is recorded, I just have to find where I got it from.
