My Nan Agnes Conor.

I am trying to trace anyone who might have any history about the Conor family who lived at 14 Queen Street, Darlington in 1909. That year my nan was born to Sarah Jane Conor. She also had a daughter Elizabeth who was probably 2 years older than my nan Agnes. Around 1915 their mother Sarah Jane died in childbirth and the 2 sisters were sent to an orphanage run by the Catholic nuns as their father was unknown. We have no idea why and the family didn't keep in contact with the sisters. My nan died aged 99 and never knew her history. I would love to hear from anyone from Darlington with the surname Conor who might know anything. Thank you x
