"Out of wedlock" recorded in lieu of the name of the father of bride or groom on a parish register in England in 1880 ... yes, likely the Vicar was over-reaching protocol even within his own church admin. However, I cannot see that today's family history buffs must immediately decide that that clergyman's words were recorded on his register with the purpose to cause scorn or other adverse comment readily available to the general public to injure the couple being married. ***
BUT from a family history perspective it is actually a very positive and vital piece of information, likely based on a verbal response to the clergy's standard question "who is thy father". It helps validate the 21st century quest to become informed about nineteenth century ancestors.
I hope that Corryn, who from his profile is currently just 22, continues to pursue family history studies for there will be many times that confronting facts will need to be examined in context.
Stan, as always, has everything at hand, and I support his thoughts on checking what is actually on the civil registration.
Andrew is spot on too, values change, the intent and meanings of words change.
