It happened exactly that way in my own family. My brother and his girlfriend didn't work out at a very young age. The subsequent son took on his mom's surname. My nephew has a different surname even though he is of the male line and one day if he wants to test I am assuming we we will be an exact match. I am curently talking to some Lomenech's in France as I have just commenced a DNA project in FTDNA and got a reply from Christelle Lomenech as such:
"Hello Steven,I'm Christelle, Charles daughter. Our surname, Lomenech, appeared in Bretagne to the 11th century.In Bretagne, we have an historic language, the "breton". In breton, the origin of Lomenech is "Loc" (place) and "Menec'h" (monk).It wants to say "the place of the monk". Our ancestors thus lived near a monastery. My researches stopped there for the moment."
I guess the point being there will be a number of people with this surname over this 8-9 centuries that will not match me for one reason or another as Sandy pointed out but.....I don't know if you can equate today's social order (chaotic as far as unwed mother's etc. is concerned) with centuries past. That number seems high Sandy but that's pure conjecture on my part.
