Hi
I am not related to your Kedington Bowyer but I do have a note of a Mary Ann Bowyer being baptised on the 17th Oct 1841 to parents Thomas Bowyer 1809 and Mary.She appears on the 1851 and 1861 census living with her parents, he is listed as being a coal carter. My records indicate that Thomas and Mary had 15 children.Can't help you on the Barber side.
Regards
Brian
