Hello

I can see the birth of Ellen Connor in 1915 (Apr quarter)
Newport volume 26 page 107
As you say, there doesn't seem to be mother's maiden name listed.
You can buy the birth certificate from GRO or local register office.
Modified - I don't think that it's correctly transcribed, because Newport at that time would be volume 11a.
The correct registration should be 1839 (Dec quarter), where you can find Ellen Connor.
Kind Regards
Morgan
