I'm trying to work out which parents my Dennis Bullivant has. I have 2 possible Dennis Bullivants born within a year of each other. One says parents are Harry Bullivant and Hesther Annie Newsome. The other says that his parents are Bullivant and Bearpark. Both Dennis Bullivants were born in Sheffield about 1916 ,1918. What I can't find is a marriage between a Bullivant and a Bearpark either Rotherham or Sheffield. Can Anyone find them as I don't want to send for 2 birth certificates.
