Eric, out of about 4000 marriage records we have here and the other 1000s we have looked at, there are only 2 x 13 year old and 2 x 14 year old brides that we have seen. One was in 1762, and the others in the early 1800s. There are plenty of 15,16 and 17 year olds. We have a query on our own tree for a 10 year old bride, but of course we are going on non official records and cant prove it, one way or the other. Remember that most of the information for age are baptismal records, and if there is no manned church in the area a Circuit Minister could come once every year or two so that could deflate the age.The other thing that happened a lot was if the wife died in childbith and left children to look after, a female member of her family took up house to look after the children and the bereaved husband. Hope this helps. Larry&Coreen.
