Hi Sally.
I have a copy of the marriage certificate, if you don't I can
transcribe the info for you.
It was not unusual to take a father's name when Mother married
and the child had been born illegitimately prior to marriage.
I will look to see if there is a Parish Record of Herbert's baptism
in the near future.
My father's line lived in Burton Latimer in the 1700's.
I lived in Irthlingborough as a child for a short time and my parents
are buried in the Cemetery there.
My great grandparents lived in Twywell in the 1880's also.
Small world, well County.

Sandy
