I think we have to remember that what happened and what "should" have happened can be very different things and many people (including our ancestors) told as many lies and fantasies as happens nowadays. I came across records for four children of a first cousin of my grandfather. The first (all girls) died a few days after birth but all of them were registered by the father with the Mother being Jessie B., formerly B... However there seemed to be a problem with the marriage - no trace thereof, until it occurred to me to look later and lo and behold, Harry B., had married Jessie B., SPINSTER, in 1895, 15 years after he registered the birth of the first child, 1880, and five years after the fourth, 1890. Were these birth entries "legal" - it clearly indicates the mother was married to the father which she obviously was not. Why were they not married? Not a clue. His father had made a lot of money and risen from being a "warehouseman" to being a "gentleman" and was very busy presenting his eldest daughter's children at courts and "drawing rooms" and hooking the daughter of an earl for her son - and his son was publicly "living in sin" but lying about it! Sometimes we just have to accept the actions will never be explained logically - although I am still open to "logical" suggestions. Good luck with further searches.
